Bug #: 51189
Summary: Acceptor threads are blocked
Product: Tomcat 7
Version: 7.0.11
Platform: All
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: Connectors
AssignedTo: dev@tomcat.apache.org
ReportedBy: helinxi...@gmail.com
Classification: Unclassified
Hi,
I deployed an web application on tomcat 7.0.11, it got acceptor threads
blocked when it ran two weeks, and the mysql connections weren't released, I
guess they are the same problem. I don't whether it is a bug of JIoEndpoint.
Thanks a lot.
