Recently i get free memory critical for the particular time from tomcat6 and automatically get resolve after some time.I am not able to troubleshoot the exact issue causing free memory critical - So to troubleshoot and to find the exact reason - i wanted to know how to check the number of threads are currently running and its memory usage. After knowing the exact thread - i can check why that particular thread occupies more memory. If im wrong please let me know any other ways to check the issue.
