Well, the `[0921/150340:FATAL:cache_batcher.cc(272)] Check failed: iter != in_flight.end().` in the logs might be a hint, or a red herring (a crash elsewhere might cause false flags). Starting out with that: - If the message above is what starts the crash, turning off memcached should put a stop to that, as I think that is the only consumer of the code involved. So if we can try this, and the crashes go away, we've pinpointed a general area to look at. - It might also help to turn on the most verbose logging, to hopefully get a chance at seeing what happens right before the crash. This could help pinpoint if there's a specific timing to this (e.g. shutdown, worker recycle, etc). - Lastly, a crash dump might be useful as that allows inspection with gdb after the fact. It would be useful to know what all threads are at when this happens. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
