Segmentation Fault eventmachine-1.2.1/lib/eventmachine.rb:202

[Bogadon]

This is probably a duplicate of similar issues, but uploading this trace in case its useful.

We have been seeing this error very frequently. Unfortunately I can not speculate on the circumstance; sometimes it lasts for days, other times it crashes on start up several times in a row, then lasts for several hours.

If you need any other information I can try to provide.

Thanks for the gem.
