Issue

A panic may occur on ONTAP storage nodes running NFSv4.x workloads, especially when using session trunking or nconnect with high locking operations. The panic message typically reads:
PANIC: thread (NwkThd_XX) on cpu <X> hung for 4001 milliseconds in process NwkThd_XX

This results in a storage node disruption and loss of service.
