Cwjava.exe uses 100% utilization in LMS 3.1

Question

We have observed that cwjava.exe process nearle utilizing 80% - 90% cpu utilization in LMS 3.1
It makes that LMS server responding slow.
Please tell how to overcome this problem.

Answer 1

On which platform is LMS running?
what size does the syslog file has?
If you have Firewalls sending logs to LMS, this could bring heavy load on the server.
Another issue could be the name resolution mechanism for syslog messages and a slow or even failing DNS for these requests.
In LMS 2.6 - LMS 3.0.1 this could be enabled/disabled in
Common Services > Server > Admin > System Preferences
But it seems that they removed this config point in LMS 3.1 - at least I cannot find it...
These log files could shed some light on this:
AnalyzerDebug.log
SyslogCollector.log
Also the defined syslog filters could have an impact and slow down the process.
As a last resort, you also can try to just restart SyslogAnalyzer and SyslogCollector process and see if the problem goes away.  You should do this in a one-liner to avoid a manual resubscription of the SyslogCollector
# stopping the processes:
pdterm SyslogCollector SyslogAnalyzer
# control their state:
pdshow SyslogCollector SyslogAnalyzer
# starting the processes:
pdexec SyslogCollector SyslogAnalyzer
