Thanks for reply.
/usr/lib/rabbitmq/bin/rabbitmq-env: fork: retry: Resource temporarily
I've checked that no limit of processes was reached (over 300 proc. were 
I was able to start new processes. May be there was a file lock on one 
of the (configuration?) files?
This error disappeared when local rabbitmq broker have become able to 
see other brokers.

Most of all I'm interested why 3 nodes crashed at once and why following 
message appeared:

     =ERROR REPORT==== 14-Feb-2012::19:13:47 ===
     ** Generic server <0.1093.0> terminating
     ** Last message in was {mnesia_locker,wosnfs at dell39,granted}
     ** When Server state == 5
     ** Reason for termination ==
     ** {unexpected_info,{mnesia_locker,wosnfs at dell39,granted}}

Following error messages may be the consuquece of this.
Look forward to results of your investigation.

P.S. better way to recover cluster is (to leave cluster if possible), 
clear mnesia on crashed nodes and rejoin them?
