We're using cewolf 0.10.2 on tomcat 4.30 with a oracle 9i backend. The problem is that the charts will randomly not display. I can see the request going to the servlet but it just blocks on the requests and never returns. We have 4 charts on one jsp page page that each have their own dataset producer. In development we've had no issues and can't reproduce. This appears to occur especially when the server is left alone for several hours.
The charts themselves are not very complicated and the sql executes correctly otherwise. Again, nothing goes to the log.
