Subject: Mongo application fails to stop thread MongoCleaner with redeploy or restart Tomcat
Print | Individual message | Show original | Report this message | Find messages by this author

I have an issue with my application based on spring-data-mongodb (101
release) and I use the mongo-java-driver 2.8.0.

When restarting Tomcat I get this message:
SEVERE: The web application [/sky-rest-provider] appears to have started a
thread named [MongoCleaner1055191651] but has failed to stop it. This is
very likely to create a memory leak.

When redeploying i get this message:
SEVERE: The web application [/sky-rest-provider] created a ThreadLocal with
key of type [com.mongodb.DBTCPConnector$1] (value
[com.mongodb.DBTCPConnector$1@346f76f9]) and a value of type
[com.mongodb.DBTCPConnector.MyPort] (value
[com.mongodb.DBTCPConnector$MyPort@543efe7e]) 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.

and indeed after a few redeploys I run into OutOfMemory:Permgen space
error. I thought this was fixed in version 2.6, see link:
https://jira.mongodb.org/browse/JAVA-306.

Can someone give me some clues of what's going on here. Is there something
else I have missed? Couldn't find anything usefully with an
internetsearch... Time to ask the experts.

What is your tomcat version/config? How are restarting/redeploying?

Hi Scott,

Thanks for looking into this. I'm using Tomcat-7.0.19. I'm deploying with
the maven-tomcat-plugin. But  I get the same error with a hot-deploy from
within eclipse or by restarting/shutdown of Tomcat . Mongo is a singleton
which is instantiated   by Spring.

Can you run a debugger, or write some code to verify that there aren't
multiple instances, because I've seen spring environments where the
configuration believed to be correct did not ensure it was actually a
singleton.

Since your setup is not trivial and there are many options which could be
affecting the config can you provide a simple reproduction case someone can
run and debug? It is probably best to file this as a java jira issue since
it will require reproducing it with whatever you provide:
http://jira.mongodb.org/browse/JAVA/

Hi Scott,

I created an issue here, https://jira.mongodb.org/browse/JAVA-595 . I have
made a simple webapp without Spring interference. This solved the error
message on shutting down. However the error message still appears on a
redeploy, though it's slightly  different. It says now:

SEVERE: The web application [/MongoReporter] created a ThreadLocal with key
of type [com.mongodb.DBTCPConnector$1] (value
[com.mongodb.DBTCPConnector$1@6c747b55]) and a value of type
[com.mongodb.DBTCPConnector.MyPort] (value
[com.mongodb.DBTCPConnector$MyPort@534d4113]) 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. (.. more or less the same)

Hope for the best,

Gert

Hi ,
Is there a solution for this issue.. I mean Gert , if you can share your
code snippet for resolution it would be great (w.r.to spring context).

Hi,

Sorry, but I never found a solution to this problem. I reported this to
jira.mongodb.org and have been waiting patiently... for 3 months now.. I
hope they will fix this one time. In the meantime I have taken the my
application into production and actually never run into problems, because
of this issue. But it's very irritating problem when you're developing, the
frequent restarts of the Tomcat server causes rapidly a OutOfMemory:Permgen
space error

Gert
