Occurrence location
LinkedHashMap is thread-unsafe.
Yeah, that's definitely an issue with the LRU Cache. How often does it happen? Do you have a way to reproduce it regularly?
It's not thread safe:
see:
apollographql/apollo-kotlin#2878
apollographql/apollo-kotlin#2844
looks like using https://github.com/ReactiveCircus/cache4k could be a solution?
This crash happened by chance.
Our current solution is to use Ktor provide thread-safe ConcurrentMap to replace LinkedHashMap.
Making sure we use the same coroutineContext when loading a cached resource might be the issue. Idk have to look into it more.
but then again I don't think using a suspend there would be ideal 🤔
https://github.com/touchlab/Stately is another option
try 0.9.0 lmk if you have any problems. I switch it to being backed by stately's ConcurrentMutableMap
