> Project: ZooKeeper
> Issue Type: Bug
> Components: c client
> Affects Versions: 3.6.2
> Reporter: Xiaotian Qi
> Priority: Critical
> Attachments: 0001-ZOOKEEPER-3944-Fix-sasl-memory-leak.patch

>
> I find this memory leak through sanitizer.
> [Here|https://github.com/apache/zookeeper/blob/master/zookeeper-client/zookeeper-client-c/src/zookeeper.c#L664-L665]
> within zookeeper_close() it destroy the client and reset it to NULL. This
> client is created using calloc()
> In zoo_sasl_client_destroy(), the client is not freed, neither within
> zookeeper_close().
> I would suggest add a free() before setting it to NULL in zookeeper_close
