HI @vevo-sterling-li,

Thanks for reporting this. Looks like a race condition between persistDiffOfUserAgainstLastSentToServer (which happens when you make an update to a user attribute) and modifications to the user state by our background flush. There should be mutual exclusion in there, but we appear to have an issue.

Do you have any idea of the number of occurrences of this issue in your implementation?

Thanks,
Wenzhi

We got about 600+ this crash in the past 14 days.

Hi @vevo-sterling-li

Updating to let you know that we've identified the cause of this issue and are actively working on the fix. The fix requires a non-trivial amount of dev work and we want to test it thoroughly, which is accounting for the delay. We plan on releasing the fix next week.

Please let us know if you have any further comments/questions regarding this issue.

Thanks,
Brian

@briancaw Thanks for the heads up.

@vevo-sterling-li,

The recently released SDK 2.20.0 has the fix for this issue. It would be great if you could confirm that you do not see this issue anymore after updating to this version.

Please let us know if you have any further comments/questions, and thanks again for reporting this.

Thank you,
Wenzhi

@Wenzhi Thanks! We will update it in our next release.
