GWIA server needed to be rebooted today (sles11sp3 / oes11sp2, running
gwia 2012sp2.

Now, every few minutes, I am getting an email with the message:

The communications link to the Groupwise mail system is back up.

I got looking at ulimit settings, but not sure if the changes I made
have taken effect. Added the following to the limits.conf file:

* soft nofile 2048
* hard nofile 65535

Anything else to check?
