> Key: DRILL-7035
> URL: https://issues.apache.org/jira/browse/DRILL-7035
> Project: Apache Drill
> Issue Type: Bug
> Components: Client - C++
> Affects Versions: 1.12.0
> Reporter: Rob Wu
> Assignee: Debraj Ray
> Priority: Major
> Labels: ready-to-commit
> Fix For: 1.16.0

> [~debraj92] found that when under some circumstance the SaslAuthenticatorImpl's sasl_dispose() function will crash out at destruction. The incident seems to be random and only when certain authentication and encryption combinations are used during connection.
> After digging a little deeper, I found that when BOOST communication error occurs, the shutdownSocket (eventually triggering sasl_dispose()) could be called from various threads resulting in a race condition of freeing the handle. This can be reproduced with the querysubmitter. This is reproducible since 1.12.0+.
> [~debraj92] will be adding a patch to resolve this incident.
