ActiveMQ and NFS mounts
I have a Continuous Integration system that runs on an NFS mount. I'm getting errors about ActiveMQ not being able to obtain a lock, which I've seen before in my code coverage tools, due to our NFS mount.
The only broker we have running during a CI test case is a VM broker, so I tried appending "?dataDirectory=/tmp" to the VM URI to move the journal to an actual disk but I get the same failure (we aren't using a XML config for a VM broker, so I'm trying to configure it through the URI). Is there something I'm missing or something I can try to avoid the locks? I don't care that it can't get a lock because it's just a CI test case, but it's causing our entire build to fail. Any ideas?
Thanks!

Re: ActiveMQ and NFS mounts
Posted by Gary Tully <ga...@gmail.com>.
use create=false on your vm: urls, so that they won't create a broker,
just connect to an existing one. Also, waitForStart can cause it to
return after a timeout if it cannot connect.
see: http://activemq.apache.org/vm-transport-reference.html

In the one VM connection we had, I changed it to be TCP and it still was attempting to start a VM broker and failed with the same error. I'm pretty much at a loss at the moment.

Subject: Re: ActiveMQ and NFS mounts
It looks like you're running out of file locks at the operating system
level. You'll have to do a bit of research to see what the default
resource limit is for the max number of file locks allowed on your
operating system and see how to change it. This can happen whether or
not you're running with the store on an NFS mount, it tends to be more
prevalent with NFS though because NFS doesn't always support file
locks, or typically the server process that manages distributed locks
isn't running. In this case though you're hitting a kernel resource
limit for file locks.
Or worst case you could probably switch to an in-memory store for your
CI builds and avoid the issue altogether.

Subject: ActiveMQ and NFS mounts
I have a Continuous Integration system that runs on an NFS mount. I'm getting errors about ActiveMQ not being able to obtain a lock, which I've seen before in my code coverage tools, due to our NFS mount.
The only broker we have running during a CI test case is a VM broker, so I tried appending "?dataDirectory=/tmp" to the VM URI to move the journal to an actual disk but I get the same failure (we aren't using a XML config for a VM broker, so I'm trying to configure it through the URI). Is there something I'm missing or something I can try to avoid the locks? I don't care that it can't get a lock because it's just a CI test case, but it's causing our entire build to fail. Any ideas?
Thanks!
