jBoss generating many java processes

[alxreds]

Hello

jBoss generating many java processes, how i can optimize this on Limit 

VIRT   RES  CPU%  MEM%   PID USER	NI S	TIME+ IOR/s IOW/s	NAME
27.0G  3.9G  2380.7    6.2     16536    root	0 S	8:43.56      0   0	java

ps -T 16536 | wc -l

1628

CPU	%user	%nice	%system	%iowait	%steal	%idle
all	55.84	0.01	0.57	0.24	0.00	43.34

Thanks !

Maybe I'm missing something, but this looks like a single process to me. What version of JBoss AS/EAP or WildFly are you using?

As you can see the PID ist the same for all rows. So it's the same process.

The SPID differs, this is the thread id.

On Linux the ps command shows a line per thread, not per process.

But nevertheless the number of thread is quite huge.

My apologies I definitely read that command wrong . So it's not really 1628 process but likely a single a process and the rest are threads. You could probably get more information by taking a thread dump to see what is consuming all the threads.
