Hey @Yann_Jouanique ,
Until recently we’ve been unable to reproduce your specific issue. Recently we fixed a memory leak that was discovered due to some reference counting issues between the SDK and v8 (https://issues.couchbase.com/browse/JSCBC-881). Upon fixing this leak, we are now seeing a segfault during shut down of the SDK and are investigating it directly (https://issues.couchbase.com/browse/JSCBC-884). Hopefully we should have a fix for it in the near future and it’s likely that this is the same issue you are encountering.
Cheers, Brett
