bouncing source.squeak.org

Chris Muller-3
I just looked at the image and there were bunch of processes hung up on one or another of two critical blocks; although it did not appear that either was part of the call stack of the other.

One of them was using a Semaphore instead of a Mutex, so that is suspicious.

There were so many, it wasn't evident what the root cause of the issue was, so I decided to bounce the server and will monitor it over the next days to see if the issue returns.

Very helpful would be to know what version it failed on..


Yes, that'd be helpful. But I'm afraid we only have a call stack at the moment. Interestingly, the error only seems to occur occasionally, so maybe we need one more retry somewhere in the updater? Obviously, the updater needs to be as bullet proof as possible, because it's used to build new trunk images.

Could it be related to the timeout we experiment each time we commit a package?

It could be.  I never experienced the timeout myself, so wondered whether it was doing a GC at that moment.  It could have been this..
