The smbc.rte driver must be MUST more robust against IP address changes on a file server!!!!

We have a NAS "cluster" from which we're mounting CIFS shares. We must use SMBv3 to be compliant with our InfoSec department. However, when an IP changes in our cluster, it's registered with DNS, but the smbc filesystems UTTERLY lock up. They don't timeout, they don't eventually detect the change, and the only way to break the lockup that anyone (including IBM support) has found is the reboot the entire AIX LPAR.

 

That's incredibly business-disruptive for a single network filesystem going down! Please rebuilt smbc to be more robust in the sort of situation we're seeing here. I doubt it's all that uncommon and the problem is making it very hard to use AIX in the context of other modern OSes.
