Hello @Farshad Mohajeri, thank you for your reply. There is no error reported in the file at the time of the node failure. I am sending you the node and hyperserver log files to your private contact with the topic name. When you can, could you please do an analysis to see if I am missing something. Thank you.

Good afternoon @Farshad Mohajeri. I still have the problem of node crashes. As previously reported, we solved all the AV and memory leak problems in the application, but the problem persists. When there are few sessions, the error does not appear. It only starts to crash nodes after 90~100 sessions. Do you have any tips that can help me find a solution to the problem? I recently increased the server resource, which was already sufficient. I modified some hyperserve parameters in search of a solution, but nothing changed.

If I update Indy, could this be a solution, or is the Indy that appears in the log specific to Unigui? Kind regards.

@Farshad Mohajeri If you could send me a private contact or platform, I will send you the complete log files for every week or month. Kind regards.

Hi Farshad, thank you very much for your reply. As mentioned, there is no trace in the node log, only in the hyperserver log. Since our last contact, we have resolved all memory leak and AV issues. Kind regards.

There are already other topics about the same problem and it never gets resolved. It happens to me every day, but randomly, we only detect it in the log created in the server module (Exception) on the production server, making it impossible to generate a test case, so the unigui team just keeps going without looking for a solution. It is unlikely that anyone will be able to generate a test case. I have already given up on finding a solution to this problem.

I would also like to know how to solve this problem. I've seen several posts here on the forum about this subject but none have a solution. Yours sincerely

Hi @eduardosuruagy, Could you attach a simple example so we can test it. I was unable to replicate your case.

Thanks @eduardosuruagy, I will test it and get back to you here.

Hello, I also keep detecting the error every day: Messsagem erro: Config Option: OEC4->bodyBorder:false<br/>is refering a previous request,<br/>it's not allowed in AJAX request or JS handler.<br/>Use equivalent Public Property or Method instead. In my case it is related to a UniDBGrid but I cannot simulate how it happens. This error is complicated. Any suggestion is welcome. Thanks!

I have the same problem on the system, when this error occurs it is recorded several times in the log. @Farshad Mohajeri or @Sherzod Do you have any tips to help us identify the problem? Thanks!!

Updating the topic, we can look at the browser console at the moment the node crashes, the message below is displayed: If anyone has been through this, could you give some tips? Yours sincerely.

Hello @Weslley Capelari, Thanks for the answer. Unfortunately in my case, the project in question uses native HyperServer "exe" for application management and not IIS. We even have other projects that run with ISAPI but we do not have the problem mentioned here in this topic. Anyway, thanks again for your help, I'm sure this information will be of great help to other developers here on the forum. Yours sincerely.

I have the same problem, does anyone on the unigui team have at least a suggestion of what it could be? In my case the Ajax event is: bclose Log: Ult.

Hello, I'm still trying to solve the problem of my application closing unexpectedly. I'm dealing with memory leak problems using (ReportMemoryLeaksOnShutdown := True;) and testing function by function. Even so, I think it may not be the solution to the problem, I'm trying to record all the application's exception logs but the class I use in the VCL doesn't apply to Unigui. An alternative would be to use the UniGUIServerModuleException event in ServerModule. I can detect the error through the AException.Message property but I can't know who triggered it. Is there a way to extract the "Form" source that generated the exception in UniGUIServerModuleException? @Farshad Mohajeri Thanks.

@Farshad Mohajeri I found a failure in the windows event close to the log time.

I'll try to implement some exception logging tool so I can investigate further. I would like to know if you have any tips that could help us identify this problem. Thank you for your attention.

We just tracked down another crash failure. The node log does not provide more details about what happens at the time of the crash. In the example below, the file above is the hyperserver log and the one below is the node log (09:37 to 09:38)

Below is an image of the node log at the time it gave the "Purgued" error. Apparently the node log did not record any error messages during the period in which the failure occurred (11:44 to 11:45) I'm getting extremely worried about this glitch. Yours sincerely

Hello @Farshad Mohajeri, thanks return. I'll investigate what also happens in the node log and post it here again

Hello everyone, we have been facing a problem for some time with the node "hanging" and disconnecting all sessions on it. I've encountered similar problems here on the forum, but all without concrete solutions. Server Settings: CPU 8X, 32GB, Windows server 2019 (Azure) Unigui 1.90.0.1567 with Hyperserver exe 32-bits. SSL: Yes (brhost) Sql server database Does not have anti-virus Firewall ports open for application We use 20 Nodes for an average of 170 connections. We are suspicious that it has to do with routines that send files to the server, but it is random. In the browser we receive error 503: At this moment the hyperserver monitor records Suspended: Soon after, the hyperserver informs Purged and terminates the node with all connections My hyperserver log file records like this: Has anyone gone through something similar? Do you have any solution? Another question, I've seen users here on the forum informed about node logging, how can I enable this function on my server? Yours sincerely

Hello @Abaksoft, your tip was of great help, however, in my case I don't need other devices to access the "server", just the computer itself that is compiling. So, I made a summary of the manual. 1 - Create the san.cnf file in the OpenSSL bin folder (C:\Program Files\OpenSSL-Win64\bin). The content of the file looks like this: [req] default_bits = 2048 distinguished_name = req_distinguished_name req_extensions = req_ext x509_extensions = v3_req prompt = no [req_distinguished_name] countryName = XX stateOrProvinceName = XX localityName = XXXX organizationName = XXXX commonName = 127.0.0.1: Self-signed certificate [req_ext] subjectAltName = @alt_names [v3_req] subjectAltName = @alt_names [alt_names] IP.1 =127.0.0.1 Replace the "X" with your parameters 2 - Open cmd as admin 2.1 - cd C:\Program Files\OpenSSL-Win64\bin 3 - Run command openssl genrsa -out root.key 2048 openssl req -x509 -days 3650 -new -nodes -key root.key -out root.pem -config san.cnf openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout key.pem -out cert.pem -config san.cnf 4 - You created the three files (root.pem, cert.pem, Key.pem) inside the bin folder. Copy these three files to the root directory where the .exe of your unigui project is located. 5 - Finally, open the Windows certificate manager (certmgr.msc), navigate to the "trusted root certificate authorities" folder and import the cert.pem file Close browser e run project.

Hello everyone, I use a self-signed certificate for the development environment created through openssl following unigui's own post (here). However, when running the application, any browser considers it insecure and in my case it makes the application slow. For now I disable ssl as it is only in the laboratory. Is there any way around this?

Hello my friends. I'm new to using SSL with hyperserver. From what I read in other posts, standalone unigui or hyperserver applications with ssl only work with openssl dlls up to 1.0.2u, is that correct? I ask because I was informed that this version of dll was discontinued by the openssl project, only the most current ones (1.1.1.10 or higher) are supported. This concerns me about data security. Is there any way to run standalone or hyperserver applications with the latest openssl dlls? PS: I am already aware that unigui applications with IIS and apache run on newer versions of the openssl dlls.
