We've been experiencing random fatal memory consumption. It's hard to reproduce, the same file can import fine 10 times in a row then explode. Note in this graph the server...

I found another example from before we increased swap from 16 to 128GB (yeah, I know). This one actually exhausted swap and triggered oom killer, but the box was totally...
