Description (partial)

Symptom:
Panic on storage controller

Conditions:
Depending on the nature of I/O workload, storage controller's preallocated fixed number of metadata buffers
get exhausted before the I/Os are flushed to the persistent storage leading to a panic. 
The likely hood is higher in disaster recovery environments involving large number of concurrent and 
small I/O workloads.
