[aznj]

any update on this?

[ahorobets]

@aznj the same problem.. unfortunately seems like project is not supported anymore, so i'm going to get rid off this solution in production

[naeemgul90]

@ArtemGorobets Have you found any good replacement yet?

[pilgr]

@aznj how often do you see this issue? Can you reproduce it?

[ahorobets]

@pilgr i've got 29 crash reports during last 90 days. approximately 5-6k user sessions per day

[pilgr]

@ArtemGorobets do you mean 28 crash reports along of 450000 (5000*90) sessions?

[ahorobets]

@pilgr yep. it's main crash producer in my app

[pilgr]

Unfortunately the root cause of this issue is hard to catch, especially since it happens only within ~.006% sessions like in your case. I assume the problem is with reading data on lower level which causes invalid data to parse by Kryo. But that's just assumption.

[naeemgul90]

Around 150 unique users have got this issue in last 7 days. I have around 10k daily active users. I know some of the users are having this issue. But it still hurts.

[naeemgul90]

This library is a real gem, it is so simple to use. I am hoping that it will be used in thousand of apps in the future. But the library needs to fixed the issues regularly.

@pilgr same problem occurring on my project also FYI
