Samba using huge amounts of memory (5GB) per client thread.
Upon checking the Gluster client logs, it's filled with messages such as:

How reproducible:

Steps to Reproduce:
Unsure how to reproduce, only seen this in one environment currently

Actual results:
All system memory and swap is exhausted. SMBD processes do not get killed off
when main SMB service is stopped, where as usually they do.

Expected results:
System resources are freed up and errors are not present in logs.
