[Users] uac_redirect out of memory?

[Greg Fausak]

We've been doing a little bit
of stress testing on the auc_redirect module.
Throwing 60 calls per second at it.  After quite
a while I start getting error messages like:

in the log file.  I have seen similar problems with regular t_relay
when we approach 200
calls per second.  Is this a shared memory problem?  How much shared memory to
I need to set up?

Have a great weekend!
