Quoting logs:
Memory limit set to 1585MB of 3963MB total.

The logs are here:
http://dl.transfer.ro/logs-transfer_RO-22mar-8ea6e9.7z

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,

[4428010.046315] Pid: 18777, comm: beam.smp Not tainted 3.0.0-12-server

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

 {memory,
     [{total,283178496},
      {processes,153323688},
      {processes_used,151332168},
      {system,129854808},
      {atom,1575153},
      {atom_used,1552033},
      {binary,14064320},
      {code,14557226},
      {ets,22433696}]},
 {vm_memory_high_watermark,0.39999999985562695},
 {vm_memory_limit,1662359961}]

Thank you,
 Andrei
