Version: 7.0.54
Hardware: Other
OS: other
Status: NEW
Severity: critical
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: chris.cir...@toysrus.com
We have just migrated our Vista application to a Linux 6.5 server has 12gb
memory and we are using Orcle as our DB system and are using tomcat 7 ver
7.0.54 and have catalina memory set to 1024 however it is continually failing
and getting out of memory issues. we are going to change to 2048 but I am
concerned we have memory leak issues. This is a production system that support
all of Toys R Us stores and is having a significant impact.
here is some detail from the log
