Event Viewer Errors

[Former Member]

Just upgraded from 4.1 SP05 P3 to 4.2 SP03 P2 ON 64-bit Server 2012. Previous system was running flawlessly. New system running without issues at all as well, however I am seeing some issues in windows event viewer. Several errors claiming that a server(s) stopped unexpectedly. Again, I only see this in windows event viewer. My 4.2 system is running with no issues at all. I never really checked my 4.1 to see if it was throwing these windows events. Non of the servers actually shut down, they are simply restarting. Is this possibly part of the java garbage collection process? One oddity that I have noticed is when my webi proc servers are configured to allow parallel queries for scheduling they restart about once an hour. If I disallow parallel queries they will not restart at all and slowly consume memory? Before I post any more information, should I not be worried about these windows errors because my system is performing with out issue or should the windows events concern me?

Thank You in advance,

Hi George,

It's hard to say if this is an issue based on the event viewer error and the service restarting. Typically the SIA would restart a service if it encounters unusual loads or high memory use. For indications of this, check the Web Intelligence Processing Server Metrics page for Memory high threshold count or Memory max threshold count. Then to see if this is related to the java garbage collection, check the APS Metrics page. If the CPU Usage Percentage or Percentage of stopped system during GC is high, this indicates a potential bottleneck. Or if the Number of page faults during GC is greater than 0, the system could be under heavy load with low memory. Perhaps these metrics along with a review of your server logs will help you determine whether there should be more concern.

as said already - it could be both. Normal and not.
Depends on which exact servers, how often and what exactly is being said in the messages.

If the webi processing servers are idle for an hour then they will restart automatically. It is by design.

If it is only related to WEBI processing server and if it is logged when the server is idle for an hour then you can safely ignore it.
