Yesterday i successfully upgraded to 2.0.2 at around 14:00h.
Unfortunately this issue, "daily server crash - Thread "Item Poller" does not respond to watchdog thread", occurred again 5 hours after the successful upgrade to version 2.0.2.
* application and services still running, but no dci polling values
* Error viewing last values for each node, screenshot attached in this post.
* empty dashboard graphsAny advice in fixing this issue is more than welcome.

Hi,
can you please add the following to netxmsd.conf:
DebugLevel = 7
CreateCrashDumps = yesas well as ensure that LogFile points to some file, not {syslog}, and restart it. When server hangs, run
nxadm -c "raise access"
server process will crash and dump will be generated. Send dump file and log file to us for analyze.
Best regards,

Different location. Different network. Different NetXMS server, (software new version 2.0.2)
same issue : daily server crash - Thread "Item Poller" does not respond to watchdog thread, empty graphs, no polling values
created DUMP file and log files. Attached in this reply.
Hope you can find some leads within the new information regarding this issue.

This issue has not been solved.
Have done some new troubleshooting.
-MySQL logging enabled and reviewed logging.
Maybe someone can tell me what to look for besides the usual error search.-Changed some server configuration parameters, for example in one troubleshooting 'run': increased the StatusPollingInterval from 60 seconds to 300 seconds.
and in another troubleshooting 'run' : increased PollerThreadPoolMaxSize from 250 to 500, PollerThreadPoolBaseSize from 10 to 20 and NumberOfDataCollectors from 25 to 50.Unfortunately until now the server keeps on 'crashing' daily.
Hope there is a solution for solving this issue.

FYI
For one location i configured the following settings on a NetXMS server:Statuspollerinterval 600
DefaultDCIPollingInterval 600
ConditionPollingInterval 600Although there are unrealistic values for daily operations the server has been running for more than one day now without crashing.

Unfortunately the configuration mentioned in my last post (Statuspollerinterval 600, DefaultDCIPollingInterval 600, ConditionPollingInterval 600) did not last.
Server just logged the error "Thread "Item Poller" does not respond to watchdog thread" and does not poll new values anymore and displays empty graphs again.
