Regards.

Does it disconnect every session at the same time (suggesting something external severing connections)? What appears in the Object Spawner log?

Yes it does...
what do mean for external severing connection?
as for logs "sessions disconnected"...

i can not share everything as the logs contain some important data of the server.

Is it possible that the Object Spawner is being restarted overnight? That would cause the disconnection.

If all sessions disconnect at the same time, it means this is not something specific to an individual session like a session timeout, but something scheduled. This could be a network appliance breaking those TCP sessions, or as @Nigel_Pain mentioned, stopping the Object Spawner process.

@Nigel_Pain you mean that it be the object spawner is restarted over night?

with even that how will I know if it is restarted over night? maybe a crontab or its the embedded restart....

so lets say it happens that its the Network appliance breaking those TCP sessions - what do I do for that?

or

its the Object spawner being stopped/restarted at night - where/what can I change?

If it is a network appliance, your network administrator should be able to help identify what is severing the sessions if you tell them the hosts / networks the connections are between and the time the connections are severed.

If the Object Spawner is being shut down and started again you should be able to see that in the Object Spawner log, the connections closing would probably be near the last thing in the log before it ends and a new log is created. The Object Spawner log file name includes the process ID and date/time the log was created, so you can look for the process ID changing in the log file names, which would suggest a restart.
