Hi,
I have been having to restart Apache Tomcat as frequently as once a day and
I suspect the problem is related to hibernate.
I have attached an error log from apache tomcat:
I get the following error below
ERROR BasicLazyInitializer:105 - CBLIB Enhancement failed:
com.insequence.gv.ProductOrder
then further down the log file
java.lang.OutOfMemoryError: PermGen space
I also noticed towards the beginning of the log file
13:26:55,625 INFO DriverManagerConnectionProvider:41 - Using Hibernate
built-in connection pool (not for production use!)
13:26:55,640 INFO DriverManagerConnectionProvider:42 - Hibernate connection
pool size: 1
Do I need to switch to a different connection pool and if so what?
Should I change the "Hibernate connection pool size: 1" to a number higher
than 1 for better stability and if so what number?
Thanks,
