Task Manager segfault randomly with RocksDB

[Kien Truong]

Hi all,

Our task managers are segfaulting randomly when using RocksDB state backend, any tips regarding how to debug this situation are much appreciated.

We are using Flink 1.3.2  with Yarn on Centos 7

Regards,

Kiên

Hi,

could you provide some logs and ideally also the core dumps from the segfault? Is this only happening when the job is already canceling?

Best,
Stefan
