Hi, I've posted this question sometimes ago, but did not receive any reply. Am sending it again if ever someone has got an answer meanwhile Am actually using tomcat version 5.0.28 on Red Hat Linux 6.2. What i've notice is that each time i compile my java classes, copy them to /WEB-INF/classes dir. and then redeploy my web application consisting of jsp pages, I saw the number of java process increases when I do a 'ps -aux' That is if before compilation of my java classes there were 30 java processes, then after compilation I saw 30 new java processes when I did a 'ps -aux' The problem is that tomcat does not kill the previous java processes that were associated with my old java classes. Subsequently if I do 5 compilation, I'll get (5 x 40) java processes and finally I got an 'OutOfMemoryError'. Can anyone please tell me what's the cause of the above problem and how to resolve it. thanks in advance -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

We have a servlet code which is based on 2.1 spec and we are moving to 2.3 spec. The code worked fine in 2.1 and we thought it will work fine in 2.2. The code worked when we commented the close() call. Thanks for the help.
