Hi,

We are seeing our CI jenkins server crashing frequently(atleast once in a day) with error:

java.lang.OutOfMemoryError: GC overhead limit exceeded

{{}}

We collected Heap dump and tried to analyse using Eclipe Memory Analyser tool(Eclipse MAT).We see below message in the report:

The thread java.lang.Thread @ 0x5d69c4500 Handling GET /job/<job_name>/descriptorByName/hudson.tasks.ArtifactArchiver/checkArtifacts from 10.158.222.25 : qtp1830908236-16408 keeps local variables with total size 1,949,995,728 (24.49%) bytes.

what does this mean?

In that job,we archive a file by proving variable name.How do we fix this issue?
