Re: debian running out of threads

[hanasaki <hanasaki@hanaden.com>]

executing "ulimit" from the bash shell reports "unlimited" and bash 
"ulimit -a" gives the same output for my account as for root.

I have googled for bugs and found nothing looking relevant.

The JVM memory allocations are much below system resource max.

Know of any way to find out how many threads a process uses and how many 
are free vs. available for use?
