<![CDATA[nxagentd v3.0.x crash with signal 11 on CentOS 7.2.511 64bit]]>I've tried nxagent-3.0.2258-linux-x86_64-static.tar.gz, nxagent-3.0.2357-linux-x86_64-static.tar.gz, and nxagent-3.0.2258-linux-x86_64-static.tar.gz all with the same results. Configuration poll crashes the agent 90% of the time. After it worked successfully one time if I do not run another config poll it would stay running and correctly poll dcis but if I click on the 'user sessions' tab it immediately crashes.

Server side is Netxms 3.0.2258 on CentOS 7.5.1804 and has been stable without issue.

abrt output with core and backtrace is attached.

Configuration full output as follows:

Will check static builds, looks like this is issue specific to either static linking or non-UNICODE build. Usually you do not need static agents though - generic Linux agent (nxagent-3.0.2357-linux-x86_64.tar.gz) should work as well.

Best regards,
Victor

Specific filenames are in the beginning of my email.
nxagent was started as "nxagentd -d -r 10.172.102.27"

initial config file:
MasterServers = 10.172.102.28, 10.172.102.27
LogFile = /var/log/nxagentd.log
FileStore = /var/nxagentd

This is the method I've used without issue in 2.2.x though that said I'm not opposed to compiling a static agent myself. The agent running on my netxms server which I did compile and is dynamically linked seems stable.
