7.0.54 Memory Errors
I am noticing in my tomcat logs Atlassian Crowd throws errors relating to memory. Does anyone have any ideas of what's causing?
SEVERE: The web application [/crowd] created a Threadlocal with a key of type [net.sf.ehcache.util.concurrent.Striped64.ThreadHasCode] {calue [net.sf.ehcache.util.concurrent.Striped64$ThreadHashCode@23ff18ae]) and a value of type (net.sf.ehcache.util.concurrent.Striped64.Hashcode] but failed to remove it when the web application was stopped. Threads are going to be renewed over time and try to avoid a probable memory leak

Are there *any* Atlassian products that aren't slow as dogs and leaky
as sieves? Every anecdote I hear is negative.

Read the wiki:
http://wiki.apache.org/tomcat/MemoryLeakProtection
The application logic should normally remove instances of ThreadLocal immediately after a request has been processed since Tomcat threads are part of a pool.
