We are experiencing crash of beam.smp on one of nodes in 3-node cluster (ring
128)
Distro is Ubuntu 12.04 with 16GB of memory (almost exclusive for Riak)

===== Sun Feb 15 10:02:23 UTC 2015
Erlang has closed/usr/lib/riak/lib/os_mon-2.2.9/priv/bin/memsup: 
Erlang has closed. 

Hi I've got following error in syslog 

Feb 15 10:02:23 node2 kernel: [157782.787481] beam.smp[2023]: segfault at
800005239d0 ip 00000800005239d0 sp 00007f47e3fe6d68 error 14 in
000061.log[7f463e32f000+1400000]

I'm not sure which causes the other.

000061.log was from leveldb folder but it ahs been deleted after restart of
Riak I believe

Last thing I could find in console log is AAE activity

Is it possible that AAE is causing the problems here.
