Linux Apache getting Invalid session or session Timeout just few seconds after creating

[INREALM]

Default timeout of 600000 is still present in uniGUI apache module, but the session is ending very quickly.
This is a very simple application - no use of databases or anything else.
No use of a Timer - etc.

Sometimes when I reload - it immediately shows another timeout message.

As we can see on log:
1. at 00:10:46 first user connected and session tk1HRU1ikN112DC642D created. He see only login screen

2. at 00:10:50 second user connected Qhec9XLmo3112DC6431. He entered login data and see mainform

3. at 00:20:07 third user connected xjW2BjFntU112DC66B6  He entered login data and on mainform clicked btn to show empty form (ShowAvailableBlocks)

4. at 00:20:15 next user connected and, suddenly, servermodule is restarted, all current sessions are invalid.

 

Why?
May be there are some special configurations for linux must be set?

Hello,

It must be related to Apache recycling settings. Unfortunately, Apache tends to unload modules whenever it wants. There are settings in Apache to avoid this. We have described this in our docs, but there are many Apache versions and different settings in different distros. You must make sure that Apache doesn't unload uniGUI Apache modules.

Dear Farshad,

Thank you for reply.

May be you can provide a link to this docs? I searched all on https://www.unigui.com/doc/online_help/index.html?configuring-apache-for-linux.htm and other docs pages but there is nothing new.
Current mpm_event.conf config:

StartServers            1
ServerLimit             1
MinSpareThreads         50
MaxSpareThreads         75
ThreadLimit             64
ThreadsPerChild         50 //increased from 25 to 50
MaxRequestWorkers       150
MaxConnectionsPerChild  0 //living unlimited, no clearing

Additional information:

Apache is killing current unigui process if any of connected users is closing browser.

May be there is a setting to detect and block this action on Unigui side?

unigui module can not prevent unloading but there must be some settings on Apache side.
