Your Jenkins instance is experiencing high Java heap utilitzation.
CloudBees Jenkins Enterprise
CloudBees Jenkins Operations Center
Operating System: Linux
Request the jenkinsjmap.sh script via a Support Ticket.
The jenkinsjmap.sh script will need to be made executable by running:
chmod +x jenkinsjmap.sh .
Your environment should be configured as documented in Prepare Jenkins For Support.
If you are experiencing high Java heap utilization please collect the following data
while the issue is occurring:
Generate a Support Bundle.
Run the jenkinsjmap.sh as the root user in one of the following modes:
./jenkinsjmap.sh PID - for default mode which generates jmap -heap output and jmap -histo output
./jenkinsjmap.sh PID 1 - for heapdump mode which generates jmap -heap output, jmap -histo output, and a heapdump file binary format
The data will be generated in the same directory where the script is ran.
Upload the Support Bundle to your support ticket for review. Compress the data generated by the jenkinsjmap.sh script and upload
it via our upload site. Please update your support ticket with the name of the file. Please note that the Support Core plugin v2.35
and higher will include the verbose gc logs. If you are using an older version please include the verbose gc logs in the compressed
data uploaded to our upload site.
