Sorry, I can't provide more informations on this version because I don't use it anymore, I can just corrected myself, it was not a 2.6.32.8 kernel but a 2.6.32.7 backport debian kernel, which had been recompiled.
Because of this problem I took the oportunity to change to a 2.6.32.26 kernel, however as there was nothing on the changelog or bugzilla about the resolution of this issue we have applied the patch found in bugzilla which revealed this problem:

Then I realised that all of my four crashed boxes were pacemaker/corosync clusters and pacemaker uses lots of RT priority tasks.
