Crashlytics report - NSOperationQueue 0x1c482b240 (QOS: UNSPECIFIED)

[brurend]

Description
I still haven't been able to reproduce this crash consistently but it been happening every now and then according to our Crashlytics. Also we haven't changed anything significantly with out cluster implementation so I'm not sure what could be causing it.

Crashed: NSOperationQueue 0x1c482b240 (QOS: UNSPECIFIED)
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000000

I can send you the full stack trace if it helps.

I added a name to the OperationQueue. Hopefully that might help identify the queue. Can you send the full stack trace?

[brurend]

Just an update, it happened a few more times during the weekend. Let me know if there is anything I can do to help investigating.

[efremidze]

What version of Cluster?

[brurend]

What version of Cluster?

3.0.2

[efremidze]

Is it reproducible if you downgrade to 3.0.1?

[brurend]

I know it never happened at version 3.0.0, I will do some testing with 3.0.1

[efremidze]

I've reverted 2.0.2 for now. Needs more investigation.
