cwjava.exe uses 100% utilization in LMS 3.1

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.


Re: cwjava.exe uses 100% utilization in LMS 3.1


it is possible to look on the server which module of LMS is behind the cwjava.exe because ciscoworks uses a lot of cwjava.exe for its processes.

I use the freeware process explorer to get more informations about the processes.

perhaps with that it is possible to figure out which part of LMS is responsible for the high load.

I have checked it and found that syslog collector is responsible for high CPU utilization.

Please tell me how  to overcome this

I don't have a solution for that at the moment.

But have you checked the syslog.log file if there came a lot of messages in?

Is there a backup or purge or something like that active?

Re: cwjava.exe uses 100% utilization in LMS 3.1

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:



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
