Thank you Trond.
There was a leakage in the application and we have corrected it. After doing a load test till now no problem is showing. Also the thread count is not increasing much.

Hi,

patches etc.. I'll let someone else answer that.

I'll venture a guess here, I might be wrong.
IIRC this is b50 of 9.1, i believe b58 was the final release of 9.1,
thus it's for a late beta of the same,
thus for b04 of 9.1_02, which is later than b58 of 9.1 then yes i
believe the fix should be in.. i can't say for sure, please corrct me if
i'm wrong
This blog
http://blogs.sun.com/GlassFishForBusiness/ has loads of
information on patches available to customers that have purchased support.

You can do both.
In the admin console go to
Application Server/JVM Settings/JVM options
Add GC settings as JVM Settings like:
-verbose:gc
Then set the number of settings you need for the verboseness of the
logging like:
-XX:+PrintHeapAtGC
-XX:+PrintGCDetails
if you want to route the gc logging to a separate file (not to jvm.out)
then set
-Xloggc:/tmp/gclog (obviously replace with a filename of your own)
All this can also be done using asadmin like:
asadmin create-jvm-option "-verbose\:gc"
asadmin create-jvm-option "-XX\:+PrintHeapAtGC"
etc..
note the escaped syntax for the : character

Dufficult to say. the "unable to create new thread" may be a result of a
too large heap with resulting too large stack sizes for the threads, you
can try to reduce the stacksize.
Please google the exception.
However since this happens after a while it may be that you have a
slowly accumulating memory leak somewhere.
