tomcat hangs when connetion pooling used

[Mahesh Viraktamath]

Hi,
I am using connection pooling for all the database transactions. I am using
the following:
MySql: 5.0.22
tomcat : 5.5.X

Now the problem is when I run the application, it can't get the connnection
from the connection pool. I tried everything like dumping all the waiting
threads, killing all the tomcat processes but nothing seems to work. I can't
revert back the results. I want to run the application as I was before.

Any suggestions for closing all the connections (if open at all) or anything
else so that I can run mu application as earlier.

Thanks in advance,
Mahesh
