Date Tue, 23 Sep 2008 19:21:16 GMT
Guys,
               As a load tester should I have to worry about the INFO 
messages mentioned below in this thread ....I am getting no clue as to 
where they creep from ?Is it Tomcat problem or our application problem? 
Any insights ?

Re: Tomcat6.0.18+Log entries upon shutting down TomCat






Hi Subhrajyoti,

I don't know an answer for your question, but I got exactly the same 
problems after upgrading from Tomcat 6.0.14 to 6.0.18. This problem 
happenend when using APR. After switching back to 6.0.14, my problem 
disappeared. Are you using APR, too? I think this is worrisome for an 
application, because my tomcat started to freeze completely after all 
threads had been in this 'waiting for deallocation' state.

Best regards,

Heiko
