HEELP I have a serious problem. I get a LOT of broken pipe exceptions
on our live system. It has taken up 3 gig of data in the log file in
just 11 days.

We are running on Redhat 4, Apache/2.0.52 and mod_jk, and tomcat 5.5.15
and MySql 4

Below is the log from just restarting the server...

what could be causing this?? the DB connection pool which is old and
buggy? or some tomcat related stuff??

The reason three pools are started is that the app is running on 3
databases (the physical database management system resides on a
different machine in the same rack).

There seems to be nothing to do with JDBC or
database communication in these failures.
