Thanks for your input on this issue yesterday. I read the notes in more detail
and have a better understanding of the arc cache. We have left the backup to
do a full backup every night and will watch the swap space expecting it to fill
and then the arc cache should free up some swap space.

Have a read of the ZFS Evil Tuning Guide
(http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide#Limiting_the_ARC_Cache)
- it should tell you how to check the current size of your ARC cache (compare
pre and post backup cache size), and how to set an upper limit if that's what
the problem is.

Are you using ZFS?
Is it the ARC cache filling up as each file is read by networker?

Hi, i have confgured a new backup of a solaris 10 server using networker 7.5.1.
When the backup starts the backup of data is successful but the swap space on
the server is being used up. The swap space is not free after the backup and a
reboot of the server is required to free the swap space.
The server has 16gb of swap space and a level full backup has used up 8gb of
swap space. A level full backup of all savesets is just under 8gb in total and
there are not lots of small files. We can watch the swap space being used up as
the backup progresses.
The networker server is windows 2008 running networker faststart 7.5.1. The
backup is to lto4 devices on a quantum i40 library.
Has anyone seen this problem before?
Is this a know bug?
Thanks, Mark Wragge
