Subject RE: Memory leak in using SSL with Tomcat 6.0.18
Date Wed, 04 Aug 2010 12:40:22 GMT
Hi Mark,

I am trying to apply the patch that is available for the fix below:

However, after giving the below command, putty simply hangs.

patch sslsession-memory-fix.patch

I am using Red hat Linux with Apache Tomcat 6.0.18. 
Another issue: Do I need to update the tomcat-coyote.jar along with this patch?
Please refer the below text from the above link:
" If you apply the patch, update tomcat-coyote.jar.."

Can you help me on this please?

I'm pretty sure the fix you are referring to was fixed in 6.0.21, not

I suggest you read the bug report and compare the details there to what
you are seeing to determine if they are the same.
