I’m using VisualVM to profile my web app on my pc. I want to see if there are any memory leaks and such.
I’m running Tomcat 6.0.29 and jdk SE 1.6 (with update 22). I should note that I downloaded jdk1.6 so that I could download and use VisualVM. My classes are compiled under jdk1.5 though.
After accessing a JSP page that displays images that are retrieved from a servlet (which in turns retrieves them from a db), Tomcat shuts itself down and the profiling in VisualVM stops since Tomcat is no longer running.
A hs_err_pid.log file is generated and it has logged the following :
Note that the spyder.servlets.ImageProcessing.ImageProcessingServlet is the servlet that handles image resizing, display and similar functions.

I don’t know what to make of this. What specifically is the error here?
What’s strange, is that when I restart Tomcat and access the jsp pages again where the ImageProcessingServlet is used on the page…the crash doesn’t happen. I just want to be sure this isn’t a serious problem…and one that I will have to be concerned over when my app runs on my vps live.
Well, it rather is a serious problem – your JVM is crashing. There’s not much you can do to debug this, either, all you can do is upgrade your JRE to a later version (the current is 1.6.0_23, as of now) and hope for the best.
edit: You’re not alone, either.
