Try the latest MySQL driver (3.08). I had a similar problem recently with a StackOverflowError that was solved by upgrading.
3.08 lists "infinite loop with Connection.cleanup()." as one of the fixed bugs, which is what I suspect was causing the overflow problem. You'll still have to contend with the MySQL connection which times out after 8 hours, but you should be able to check for that and reconnect if necessary or use the autoReconnect parameter (http://www.mysql.com/documentation/connector-j/index.html) Steve > -----Original Message----- > From: Vikram Goyal [mailto:[EMAIL PROTECTED] > Sent: September 16, 2003 6:49 PM > To: Struts Users Mailing List > Subject: Stackoverflow after DB inactivity > > > Hello all, > > I am getting a Stackoverflow error in Tomcat 4.1+ after a > period of database > inactivity, typically (3+ hours).
