Sporadic crashes with Mac 2.82

[Benabik]

Ever since updating to 2.82 Transmission on my Mac, I get random crashes. It doesn't seem to be connected to anything I'm doing, as it will often happen when I load up Transmission to run overnight. I've attached a copy/paste of the detailed crash log from the report dialog.

Can you post a crash log from a build from ​https://build.transmissionbt.com/job/trunk-mac/?

I downgraded to 2.81 and am still getting the crashes. Perhaps this is related to my torrents? I am downloading the games from the most recent Humble Bundle, so there are a lot of torrents all with web seeds and I have speed limit turned on so other people can still use the internet.

I likely associated this with the 2.82 upgrade because it prompted me to update when I went to add the torrents and I haven't had this problem before. I'll upgrade to 2.82 and see if there's anything I can do to stop the crashes. (I've attempted to attach a crash log from 2.81 for comparison.)

Benabik, please download and test the latest .dmg from ​https://build.transmissionbt.com/job/trunk-mac/. Revision r14182 may help with this issue.

[Benabik]

I downloaded r14203 and it seems more stable. I'll leave it running today and see what happens.

[Benabik]

It ran most of the day and it was much more stable. (I had previously only gotten a few hours at most.) At first glance, it appears the crash log is from something completely different, but I'm posting it here in case it's related.

[x190]

Benabik, your first two CR's are related to speed-limiting webseeds. The one for r14203 is something different. It would be best to open a new ticket for your latest crash and please provide as many relevant details as possible. If you get the 'curl_easy_pause' crash again, then post that here.

Just attached my crash log, I'm having the same problem. Crashes while I'm downloading with a rate limit.

yaomtc, please see comment:5.

[yaomtc]

I got r14205, and it's been downloading for several hours. No crashes. Looks like that's fixed!

[livings124]

Nice!
