Issue/Introduction

The catalina.out file shows a number of messages indicating that the brightmail web application may have a memory leak.

catalina.out:

SEVERE: The web application [/brightmail] appears to have started a thread named [File Reaper] but has failed to stop it. This is very likely to create a memory leak.
SEVERE: The web application [/brightmail] appears to have started a thread named [LogAgentTask_1] but has failed to stop it. This is very likely to create a memory leak.
SEVERE: The web application [/brightmail] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [[email protected]]) and a value of type [com.symantec.smg.controlcenter.internal.mail.transport.MailTransportFactory] (value [com.symantec[email protected]4f892c41]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak. 

Cause

The messages are created by the tomcat web application server as a warning that a thread has been created but not stopped.

Resolution

These messages are cosmetic and can safely be ignored.
