Re: 1GB Buffer Pool Memory

From: Matthew Glanville

I have seen those errors on one ADSM server when running SUN Solaris 2.6
and ADSM 3.1

If I remember correctly, It didn't appear to be memory related.  It just
was that too many things were going on at once on the TSM server (too many
threads?).  I reduced the number of volumes in the disk pools (there werer
over 60, 1 GB volumes, changed that to 6, 10 GB volumes ) and reduced the
maximum sessions setting and never had that problem again.

Maybe this will help...

I am running it as root, with no limit.  I have 4GB real memory, and 3GB
of paging space, 1% used.
