Since Monday I have been seeing "terminated by signal 11" messages in my 7.4.6 + Slon 1.0.5 system,. but only on the master
I've done a dumapall, initdb and restore , which reduced the frequency but I still get them 6-8 times a day.
After turning up logging it seemed to die when calling a very small table (2 rows, 4 columns, 8 char text strings), but manually selecting caused no issues, so I then took a hit and shutdown the system and swapped out the RAM (from earlier list suggestions).
This seemed to work until 7 hours later when the problem has reappeared, at a higher frequency too.
It is ONLY occuring on the master, not on any of the leaf (replicated) nodes, and seems to be triggered by a few different systems connecting (so no common code base)
