[jacorb-developer] Jacorb corbaloc call hangs when using Unlimited Strength JCE

[Alka Nand]

We have been using JACORB 3.0 with JCE with no problems for several years.
We use TLS and secure communications very extensively. Recently we decided
to upgrade to the Unimited strength JCE to make use of 256 bit ciphers.
Unfortunately we started seeing threads hanging when trying to connect with
a Server that is down - cannot be pinged. I have the corba timeout set to
30 seconds and before we upgraded to unlimited strength JCE it would always
timeout after 30 secs.

We have a Monitor set up that has a thread pool that tries to periodically
connect to the various server. After running for about 2-3 hours I saw that
one of the threads got stuck while trying to connect. There were 3 servers
that were down and in the same ping cycle all the three client threads
trying to connect to these TAO servers got stuck.

On doing a pstack it looks like the threads are stuck at this point

I would really appreciate any input regarding this issue. As I said we are
using Jacorb 3.0 and our server are running TAO. In any case this is
happening only when the server is down.

Thanks
