[rabbitmq-discuss] exessive memory usage and blocked connection, even when no messages left

Wed May 18 17:15:39 BST 2011

2.4.1, should have been more specific. the OS is ubuntu 10.04, btw.

there's a lot of warnings in the log about memory usage, but it's more
or less the same thing over and over again:

=INFO REPORT==== 18-May-2011::14:37:20 ===
vm_memory_high_watermark set. Memory used:3327376104 allowed:
3006570496

=INFO REPORT==== 18-May-2011::14:37:20 ===
    alarm_handler: {set,
{{vm_memory_high_watermark,rabbit at rfmmqstaging01},[]}}

then I found this, not sure if it's important (pasted it into a gist):

https://gist.github.com/978897

this is the version of erlang:

Erlang R13B03 (erts-5.7.4) [source] [64-bit] [smp:8:8] [rq:8] [async-
threads:0] [hipe] [kernel-poll:false]

I've been watching the management UI since I posted my first message
(almost an hour ago) and the memory usage hasn't gone down. can a node
get bad? the other nodes look ok, but the one that's in the red in the
screenshot is still in the red. no connections to the server for an
hour.
