David,

Are you using a JDBC connection pool? I've seen Tomcat "hang" in this
way when there is a mismanaged connection pool (i.e. connections are
being left open until the pool runs out). Something to check any way...

Subject: Tomcat 4.1.31 hangs after 2 days .. any idea on what going on
.. ?... please help

Hi all,

  I have tomcat server in production and after some time (maybe 2 or 3
days) it stops answering request.  When I acces the login page with my
browser it just waits indefinitly for the page to load.. nothing happen.

  In my webapp I have a thread that look into the db .. I know that this
thread is still working properly.  Is someone have any idea on what
going on ?.. or on what can cause the server to hang the way it does?  
Or any suggestion to troubbleshoot to find what doing on?

I go throught Catalina.log and other logs file and there is nothing .. 
no exception not a clue :-(

This site is working for a while now and I don't know if the probleme
just appears lately or was there since the beginning. 
The log file (Catalina.log) was 300megs .. I don't this as something to
do with the problem thought. 
Here is other relevant information:

RedHat9, kernel 2.4.20-43.9
Mem:       2064440    2027876      36564          0     292088

Thanks for your help.
