Subject Re: Getting negative number of pending messages
Date Fri, 04 Sep 2009 17:53:06 GMT

I'll have to see if that trick works. We solved it by setting useAsyncSend =
true. We also turned off the persistent data store (kahadb) because somehow
we were getting a few messages caught in there that weren't being delivered.
Maybe using the data store plus useCache=false would work. Its hard for us
to duplicate the issue in testing as it seems we can't quite push enough
data through it. 

We probably should upgrade to v5.2, but there doesn't seem to be anything in
the changelog that would indicate anything we need. Our sysadmin is quite
conservative when it comes to certain things. Once v5.3 is released as
stable, I'm going to try my best to get us upgrade to it.
