Hi, I have an web application which is experiencing slowdowns when sending a message. (see stack trace below). It runs fine after a reboot. But after 1-2 weeks of running, I am seeing 10+ seconds delay when sending the message. When my server is under load this can be much longer.
Any suggestions as to what I should look for? What might be accumulating in the running app that slows it down? The memory is not significantly high. I took a heap dump, didn't see anything unusual. Here's the stack trace. I took one a couple of times and it's always waiting at the same point.
