I've got a server that is running out of swap space:
+pid 37308 (mysqld), uid 88, was killed: out of swap space
+swap_pager: out of swap space
+swap_pager_getswapspace(1): failed
The strange this is, this server has a 6GB swap partition!

This isn't exactly a resource-starved machine either:

Any suggestions are welcome - what could cause this?
ps aux | sort -n +5
The latter processes need most memory.
How to
troubleshoot?
This may be normal behaviour. It depends on the processes.
Possible solutions/workarounds?
It depends also. Possible solutions are: Add more RAM, add swap (see
[1]) or run less processes.
