Weird log entries in elasticsearch.log

I got some weird errors in my ES log...

[2012-12-27 15:37:25,267][WARN ][monitor.jvm ] [Locus]
[gc][ParNew][2676426][42057] duration [9.4s], collections [1]/[3.8m], total

[669.1mb]->[707.1mb]/[1.6gb]}{[CMS Perm Gen] [33.2mb]->[33.2mb]/[82mb]}

Does anyone know what that means?

Then I got a lot of:

After all of the weird HttpChunk things ES stopped working.

Thanks in advance for any assistance!

The first part is a warning message that Java garbage collection took
longer than expected. Are you running queries with faceting, sorting
or scripting? You see these warnings often? Perhaps the es process
needs more memory. You can check this with the node stats api:
http://www.elasticsearch.org/guide/reference/api/admin-cluster-nodes-stats.html
(use the jvm flag)

I think the last error could be a result of the first warning. Usually
when memory becomes scarce ES nodes can become not responsive.
