<![CDATA[Communication session broken]]>Hi,

I installed netxms agent on Win Server 2008 R2 (netxms version - 1.2.14) and this message is appearing in event viewer occasionally:
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

Here is server log (you can also see processing of this event from event log - I setup event log monitoring), it looks like it happen after poll status:

[16-Jun-2014 16:27:02.589] [DEBUG] Node 236 "eesk-app-02" queued for status poll

If it is not important I can ignore it but is there any option how to filter this event - send all warnings / event except this one ?

Thanks and regards,
MK

Could it be bug in latest version ?

I installed client on monitoring server from this link https://www.netxms.org/download/agent_packages/nxagent-1.2.14-x64.exe (I did default install)
Change conf. file (nxagentd.conf):

MasterServers = 172.16.44.116
ConfigIncludeDir = C:\NetXMS\etc\nxagentd.conf.d
LogFile = {syslog}
FileStore = C:\NetXMS\var
SubAgent = logwatch.nsm

*LogWatch
Parser = C:\NetXMS\etc\application.xml
Parser = C:\NetXMS\etc\system.xml

xml files:
<parser>
  <file>*Application</file>
  <rules>
    <rule>
      <level>3</level>
      <match>(.*)</match>
      <event params="1">100000</event>
    </rule>
  </rules>
</parser>

added node in console
start Poll Status
start Poll Configuration

I assume that others don't have these warnings in Event Viewer so it should be something wrong here 😞
