CONTAP-766727: ONTAP Stack-Overflow Panic on QLogic FC Target Adapters During ABTS Processing
Issue
ONTAP may experience a stack-overflow panic on systems configured with QLogic FC target adapters when fabric or host-connectivity issues cause FC ABTS requests to be generated.
PANIC: thread stack overflow in SK process fct_tpd_work_thread_0 (dblfault_handler -> Xdblfault)
AND backtrace shows unbounded mutual recursion between fct_isp_process_one_resp_queue() and fct_isp_process_atio_queue()
