The number of garbage collector threads can be manually set by the user using the "-Xgcthreads" option. For example, to set the number of garbage collector threads to 3 use "-Xgcthreads3"
Problem summary
On systems with multiple NUMA nodes, the number of garbage collector threads (reported as "gcthreads" in the verbosegc output) may be set according to the processor count of a single node rather than the whole system.
Problem conclusion
The number of garbage collector threads is now set to the number of available processors of the system. . This APAR will be fixed in the following Java Releases: 8 SR1 FP10 (8.0.1.10) 7 R1 SR3 FP10 (7.1.3.10) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
