Re: Swap Leak on Solaris 9 and a posting from last year by Grzegorz Goryszewski

New information.  On the logical standby server, the total swap size plunged
yesterday morning from 14-GB to 1.8-GB when  the network admin ran a Qualys
port scan.  On the physical standby server, I don't collect OS stats, but
total swap size (not swap available...TOTAL swap size) was 450-MB a few
minutes ago and the size of the ocssd process was 6-GB.  I just killed ocssd
and total swap size jumped back up to 6.6-GB and seems to be rising steadily
and is now at 6.9-GB.  The network admin just ran another port scan on the
logical standby server and total swap size plunged from 14-GB to 2-GB and
seems to be steadily dropping.  At the same time, the size of the ocssd
process jumped from 30-MB to 12-GB.  So, we need to figure out the
relationship between the port scan, swap, and the ocssd daemon.

Thanks for responding.

 Mark,
We are running Solaris 9 and the OS is patched up with DST patches. We
have some large enterprise level servers, E20K, E6900 as well as small
servers, like v490, etc. running Oracle9i and Oracle 10g databases but I
have not experienced this issue on our servers. I can monitor some servers
to see if we are leaking swap space.

This past weekend, we patched our Production Sun servers with Solaris
patches and the Oracle DST patch.  On two of those servers which host
standby databases (one server for physical, one server for logical), we are
seeing swap space gradually drop down to almost nothing from 14-GB.  Just
had to re-boot one of the servers and the other one is not far behind.  A
Google search came up with a posting on this list from last year from
Grzegorz Goryszewski who was experiencing the same thing.  Grzegorz, are you
monitoring this list still?  Did you find a solution?  Has anyone else seen
this behavior?
