Memory limit set to 1585MB of 3963MB total.

The logs are here:
The server started at :
=INFO REPORT==== 20-Mar-2012::19:15:20 ===
and it crashed at:
Wed Mar 21 13:05:19 2012
The startup_log is from the last startup(after 13:05).
The last entry in the -sasl file is from 28-Feb-2012.
The previous runs that you see in logs was a 2.8.0 install, but it
seemed to leak memory. That's why I downgraded it to 2.7.1.
Regarding 2.7.1, it crashed a few times before but killed by OOM killer.
This was the output in dmesg:
[4428010.034014] Out of memory: Kill process 18725 (beam.smp) score 855
or sacrifice child
[4428010.034117] Killed process 18725 (beam.smp) total-vm:4978220kB,

Here is the "normal" memory usage(reported by rabbtimqctl status):
