Hello,
I am facing one crash in grpc library:
Backtrace
#0 0x00007f0a93b7547f in __pthread_kill_implementation () from
/home/tmp_work_dirs/ard/tmp-1685948391-17258/tmp/lib64/libc.so.6

Apparently the completion queue seems to be drained out, next is being
called on the completion queue, hence next is returning false, causing
assert. Is there a way to determine if this is the root cause?
Further details:
(gdb) p *((cq_next_data*)(call->cq+1))
$53 = {queue = {queue_lock = {atm = 0}, queue = {head = 139682470484976,
padding = '\000' <repeats 63 times>, tail = 0x7f0a644b34a8, stub = {next =
139682609301216}}, num_queue_items = 4},
things_queued_ever = 21872, pending_events = 0, shutdown_called = true}
Pending events is zero.
Is there any documentation to explanation how completion queue works in
detail?
