No bug, but a too long timeout. Thus changed several years ago.

Yes I see that the default timeout for the action queue was changed from 2000 
ms to 50 ms. However, for the main queue, “iMainMsgQtoEnq” remains 2000 ms. Why 
was it not changed for the main queue? Is it because the 2 sec delay in the 
action queue processing has greater impact than the delay in main queue?

Thanks

we would need to see your full config, but if rsyslog fills it's queue
(commonly
because you have it configured to send to a different machine via TCP and
the
remote machine is down), it is unable to accept new messages, and the
system
will stall.

This is part of the spec for the syslog protocol, not a bug to be fixed in
rsyslog.

There are things that are available to help throw away messages faster
when the
queue fills up, I don't remember when they were added. look for the
discard
severity and high/low watermark options for a queue.
