JVM_GC_Thread_Count_Warning

Situation Description

Garbage Collection is using not only online logical zIIPs but General Purpose cores as well.

 

Possible Causes
  1. Garbage Collection threads count is greater than the logical zIIPs online count.

 

Suggested Actions

A JVM may use more threads to perform Garbage Collection than online logical zIIPs on your system. That leads the JVM to use General Purpose cores. To avoid this you can use the following parameters to set the needed Garbage Collection Threads count: -Xgcthreads or -Xgcmaxthreads
