SGen failed to wait on a semaphore => looks like your area, Rodrigo.
Comment 2 Rodrigo Kumpera 2012-05-12 08:59:26 UTC
Chris, can you share me a reproducible test case?
I'm pushing an improved crash message in the meanwhile to help us figure this out.
Comment 3 Rodrigo Kumpera 2013-08-27 11:41:38 UTC
No test case for more than a year. Closing.
