High CPU load after upgrading

Hey there,

since we upgrade fisheye from 3.7 to 3.8.1 in gradle open source project, We're seeing high cpu load constantly caused by the fisheye process. We havn't changed anything in configuration and just using one incremental-indexer thread. Is anybody else seeing this issue. We would really like to track this down. any help and advice is highly appreciated as our server is now running with 98% caused by fisheye. restarting doesn't solve the issue. is there anything I can look for in the debug logs that might give me a hint?

 

cheers,

René Gröschke

Hi,

The best way to figure out what is going on would be to take some thread dumps during the high CPU load, or to use a tool such as jvmtop to get a better idea of which threads are taking up a lot of CPU.

We have some instructions here on how to generate thread dumps.

It could be for example, this open bug:
https://jira.atlassian.com/browse/CRUC-6593

However, there are many possible causes, so the best way forward would be to get a few sets of thread dumps at a 15 second interval during high CPU load. Please open up a support ticket if you'd like us to investigate further.

Best regards,

Dave Lahn
