Glassfish Web Services Slow to Crawl

Hi. We researched the forums and found nothing specific to our issue. We wrote some web services for Glassfish 2.1.1. We access a MySQL database through a connection pool setup in Glassfish. After a few thousand calls, the web services slow down by 500%. Even calling simple web services that do a simple SELECT will start to encounter the problem. We see RAM being consumed but no significant increase in threads or handles. We can't yet move to Glassfish 3.x. We read up on updating our Grizzly and we have assured we are closing our Statements and ResultSets. If we restart the domain we are back to fast and then the gradual decline. Any clues as to why this dramatic decrease in resources and performance? Thanks!
