It appears that my problem with IIS "losing its link" with Tomcat was actually an application problem, as several of you suggested. The JMX thread dump (very helpful over terminal services) indicated that 100 threads were locked up with Hibernate trying to get a database connection from DBCP. Upon further research I learned that Hibernate (and probably everything else) works better with the c3p0 pooling API, so I switched all my applications over to c3p0 and all is well (for now).
Thanks for all the help, Travis Haagen --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
