Hello,
We are experiencing a non-fatal exception while using Grizzly 1.8.6 on a
sporadic basis. The exception shows up with slight differences in both the
.log file and the .out file (which captures system.out).
In the .log file, we see this:
2009-04-24 16:05:22 INFO [pool-2-thread-1] (xServer.java:50) - Starting
xServer...
2009-04-24 16:05:22 INFO [pool-3-thread-1] (PolicyServer.java:33) - Starting

There are the same number of exception traces in each file.
As I said, this seems to be a non-fatal exception which we can continue to
operate through, but we would of course prefer to clear it up. Any help
that anyone can provide in figuring out what is going on would be much
appreciated.
Thanks,
