[Info-vax] A 5 minutes hang during early stage of a shutdown.

[Jan-Erik Soderholm]

Hi.
This isn't a show-stopper but I thought I'd ask if anyone
has seen anything like this before.

$ tcpip sh ver

   HP TCP/IP Services for OpenVMS Alpha Version V5.5 - ECO 1
   on a COMPAQ AlphaServer DS20E 666 MHz running OpenVMS V8.2

$

During the early stage of a normalt shutdown (with automatic
reboot), the system hangs for more or less exactly 5 minutes.

The detached shutdown process is in QUEMAN.EXE and in LEF during
this period. The queues are "stopped" as far as I could see.
There was one queue in "stopped pending". This batch queue
had one job in MUTEX (the reason for the reboot). But, I have
seen this shutdown delay even without this MUTEX problem.

I can still use MONITOR and the system is close to full
idle during the delay. No CPU and no (or very few) I/O's.

The rellevant part of the consol output is below.
Only changed real node name into "zzzz".

Regards,
Jan-Erik.

Here it shuts down as expected and the reboot always runs OK.
