Disconnect distributed system

[Victor.Ermakov]

Hello.

I have a problem with my distributed system.
My project consists of 1 server system (ID;1 ServerWeb:170.1.1.1), 2 remote systems (ID:101, ID:108) and 4 workstations (with ui manager).
When I open the user interface on a specific workstation, the connection to one of the remote system (ID:101) is broken (after 1 hour and more).

After that the message appears in the logs:
On a remote system:

In the part of the log message there is a Russian text which I cannot read.
Can you please tell us which information is written there.

I would start to look at the first highest priority error:

WCCILdist (1), 2019.07.05 04:23:27.686, SYS, SEVERE, 39, Connection lost, Send buffer limit exceeded, closing connection to (SYS: 1 Dist -num 1 CONN: 1) @ ServerWeb, [PeerItcIOHandler::sendCall]

Apparently this remote system sends too much data to the server system. You should check why this remote system sends so much data.
