All messages getting stuck in 5.10 until restart...

We’ve been having this problem for a while now but it’s becoming more
apparent as we deploy in production.

Essentially all messages in ActiveMQ get stuck until I restart it. Today
it took three restarts… then it just started working.

Here’s my config:

We’re using LevelDB… the box seems to be idle while this is happening.

There isn’t much data either. < 1GB… should all fit into memory.

It’s entirely possible it’s the client … but I’m using the official
activemq client.

I think I might try browsing the queue from the command line next time this
happens.

Any other pointers to help track this down?
