Hello Dil,

Please, observe the following:

do the people experiencing the problem have anything in common - i.e. they work in the same company at the time of breakdown? or they work in the same local network, and possibly - different network as others who don't face it?

You can also ask the users if they get this information during the active work in the system or when they do other tasks. In most installations the client will log off itself when idle. Check: module System>>Settings>>Optional features>>Idle client timeout (minutes).

This issue could also be caused by network connection breakdowns, either losing the network or the server. You can test if the connection is not broken by running the ping command from those computers (pinging the server i.e.) and check the result at the times the connection is lost.

If those ideas will not help, please, return to us with as much detail as possible.

Best regards,
