<![CDATA[Communication session broken: A request to send or receive data was...]]>I have 100+ warning 'Communication session broken: A request to send or receive data was disallowed because the socket had already been shut down in that direction with a previous shutdown call.' in the system event log. I have this problem on 2 different systems. One windows 2008 and the other 2012.
On the 2012 i changed to configuration to create a debug log.

This is a section from the debug log:

It seems that the connect was closed by the watchdog (red line) but way?

Best regards,

The strange thing is that sometimes it runs days without any messages and sometime +100 a day.

MasterServers = XXX.YYY.ZZZ
ConfigIncludeDir = C:\NetXMS\etc\nxagentd.conf.d
LogFile = C:\NetXMS\log\debug.log
FileStore = C:\NetXMS\var
SubAgent = logwatch.nsm
