Description
I’m allocating about 6GB of RAM to ActiveMQ. The problem is that this box only has 4GB free after that.
If I try to gracefully shut down ActiveMQ tries to run "stop" to gracefully request that ActiveMQ shutdown to avoid recovery on startup.
The problem is that this uses the ACTIVEMQ_OPTS_MEMORY again and since I'm setting memory settings to maximum here this simple command tries to allocate another 9GB.
However, this will fail. because ACTIVEMQ_OPTS includes ACTIVEMQ_OPTS_MEMORY which is where I set the daemon to use large amounts of memory.
I THINK the resolution to this is to ONLY use ACTIVEMQ_OPTS_MEMORY in "start"…. wouldn’t you agree?
This has a second issue where since I’ms eating -Xms and -Xmx and allocating another 6GB during stop it could trigger an OOM killer and will definitely invalidate a large chunk of the VFS page cache.
Here's a patch that fixes the issue.
It does NOT fix the issue for the 'status' command. That would take a larger refactoring of the init script and I'd like to avoid that for now since bash scripts can be fragile.
