Anyone else seen crashes like these ?

Hi,
I run Pharo 7 64-bit on a macOS laptop, where the images are kept running across sleep/wake cycles. For many weeks, it often happens that an image crashes before/after such a sleep/wakeup (not all the time, just regularly). Here is a crash dump from today (fresh image/vm from WE, nothing special loaded). Related to scheduling ? Event handling ? |
crash.dmp (10K)

You didn’t say it, but I think implied that this is new to P7? I don’t get it on P6, and haven’t noticed it in earlier P7 images. But haven’t extensively used a newer P7 image.

Its perhaps co-incidental with delay scheduling code is invoked fairly often, that its the current process when this crash occurs.To hep isolate the failure point, I would considering copying #nowTIck to a multiple series like... #nowTick1 #nowTick2 #nowTick3 etc so that all of the sender sites can be made distinct. And maybe the same for #signal senders within the delay scheduling code. One side-curiousity is I can't see where the primitive #@ is being called from. Does it indicate some loop as its trying to determine To me the "vmIOProcessEvents" in the C backtrace with a fairly deep stack into the AppKit framework indicates its related to event handling. cheers -ben |

I meant to also post a link showing the pattern of the recent primitives... https://docs.google.com/spreadsheets/d/1QzY8iL_3kvHJg1xMg1yvCFzDpQf3Tl9zuVkzfom4cx4/edit?usp=sharing On Tue, 13 Nov 2018 at 00:50, Ben Coman <[hidden email]> wrote:

Yes I mean laptop sleep/wake.
Thanks for looking into this. But I think the first step is to see if this is repeatable for someone else. It is probably some graphics primitive rather than scheduling (I am guessing here).
