qpidd critical error: Cannot lock file continues in running

Solution Verified - Updated -

Issue

A standalone (non-clustered) broker prints error "critical Unexpected error: Cannot lock" on start up. Despite the highest severity it continues in running.

Moreover, all durable queues are not accessible then (qpid-stat -q shows no durable queue present).

Why the error was hit?

Shouldn't this critical error prevent the broker from starting up?
