Hi Paul,
You're right, we rebooted the server and it's OK but we are working with SUN on how to best tune the kernel parameters to make sure it doesn't happen again. It's a bit hard when you have an old version of Universe running and it does searches to see that you have various values set. SUNs kernel tuning looks to be a bit of a black art.

SAN media server. what other app is running on this box? When you say the "defaults are much bigger than anything Symantec recommend" Does that take into account what other apps running on the box require? The defaults may be plenty for NBU, but not enough for NBU + Oracle, or whatever else is on that box. aPaul -- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dominik Pietrzykowski Sent: January 26, 2008 9:31 PM To: Jeff Lightner; VERITAS-BU@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] semaphore issue Hi Jeff, Do I reboot the master or the master and the media servers or just the media server ??? This is happening on 2 off my SAN media servers. The master and my main media server appear to be OK. Thanks, Dominik _____ From: Jeff Lightner [mailto:[EMAIL PROTECTED] Sent: Sunday, 27 January 2008 1:12 AM To: Dominik Pietrzykowski; VERITAS-BU@mailman.eng.auburn.edu Subject: RE: [Veritas-bu] semaphore issue Haven't seen it in relation to NBU but if you are sure that the semaphore parameters are all adequate it may be that something stopped abnormally and left semaphores or even shared memory segments in use at a memory address that NBU wants. In NBU 6.x there is a database instead of flat files and it is Sybase. Most modern databases use a combination of shared memory segments and semaphores for control. You can use the ipcs command to examine what semaphores/shared memory segments are in use. You can use ipcrm to remove any. WARNING: Deleting shared memory segments or semaphores that are still required by a running application can cause your system to crash. If you're not sure what can be cleared a reboot will clear both IPC types. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dominik Pietrzykowski Sent: Friday, January 25, 2008 6:20 PM To: VERITAS-BU@mailman.eng.auburn.edu Subject: [Veritas-bu] semaphore issue Anyone seen this on a Solaris 10 server ???? # ltid -v # Error in getting semaphore # Ltid keeps on dieing and it complains about semaphores. My other Solaris 10 servers are fine but I have two with this issue. Both use different hardware and no you don't need to tune the kernel on Solaris 10 as it's defaults are much bigger than anything Symantec recommend. Hope someone can help.
