We upgraded 1C up to 18.104.22.1686 version.
Clients are closing suddenly after a while work, but sessions are not closing on server side. Clients are using thin client in windows, linux ubuntu (both 32-64 bits), macOS and mobile client on iOS. Connection working via web server (both http and https protocols).
Server: Ubuntu Server 16.04.1 LTS (64-bit)
Web server: Apache 2.4.18
DBMS: PostgreSQL 9.2.1
Is there way to find out the reason of suddenly closing up of client?
