Hello Friends @ 3000-l,

Re: reboot to clear out the trash...

Why wouldn't a complete network shutdown and startup, without a system
reboot, be sufficient to clear the buffer pool memory structures?

Yes, in general this is true, and in any case where it is not true it
would be a bug...  Now the question is do bug's happen ?  Yep, and as
we find em we kill em... SR 5003-409136 as an example fixed in 5.5
GR NSTFDD8 and 6.0 Beta Test NSTFD97.  If you don't have these patches
installed, you are open to having buffers not freed on network
shutdown.  I am sure in the future we will find other corner cases that
drive situations where buffers are not freed and we will fix em as we
find em...

A lot of customers are successful never shutting down systems, but in a
past life as a system manager I found it a useful procedure to complete
Month End, Perform Backups and then =shutdown and restart the systems.
If nothing it promoted the fine-tuning of my operations staff's
execution of the system shutdown and restart procedures; beyond that
it flushed out the spooler, initialized the job numbers & cleaned
out any transient buffers and FINALLY if I was going to find out I
was going to fail to restart a system due to a hardware or software
problem, no time was better than after completion of the Quarter End
processing and a full backup!

That is another .02$, now you have .04$ and another dollar will buy you
a coffee, tax included.
