Hi,
we are using IS 6.1 and while running one of our processes thorugh scheduler, we got this error:
2010-02-10 23:55:49 HKT [ISS.0069.0018W] No threads available to run task {1#{pool min=2 max=5 size=4 inUse=5 miss=34 draw=41930 drop=0 create=5}}(Statistics Log, 10.0, 1265817290716, running)

What could be the possible reasons?

Thanks!

Seems your server is running out of memory, check for hung threads by checking long running services under service usage. If there is any long running service try to figure out the reason for the same.
Alternatively to resolve the problem you can restart the IS, it should resolve the problem.

choudhp is not running out memory but out of thread :wink:

It seems one of you’re thread pool is not sized enought. If you’re lucky, it’s not a wM pool but yours (for example, linked w/ JDBC connector).

I suggest having a look in your connectors activities and eventually enlarge there size.

Alternatively, you can generate a thread dump and check inside which one is culpit.

Good luck.
