Thanks for the response... What major headache that bug is. I shall upgrade rather than coming up with a creative workaround (I'd love to, but I need a proper fix).

I would like to know what kinds of limits there are for load on WO. How many instances of an application could I run, has anyone much experience with high loads, say 1000's of requests in the space of a few minutes? Java Monitor seems cumbersome with 100 instances.

Cheers, Corin.

PS. I like the FAQ (not very pretty but). It would be nice to see some categories if it keeps getting bigger.

Recently I have found that under a increased load there is a large number of tcp connections in CLOSE_WAIT state. When there is enough of them the adapter to no longer able to find any app (including the JavaMonitor) and the whole system grinds to a halt...

I have confirmed that WODeployment 5.2.3 is installed on Mac OSX 10.3.

Please help! How can I get rid of the CLOSE_WAIT states?

The cause is a bug in wotaskd in WO 5.2.2 and 5.2.3. The only real solution is to upgrade to WO 5.2.4.


If that is not possible, a workaround is to simply kill wotaskd once a night. It may also be possible to write a script to detect this condition and kill wotaskd.
