From: CasinoSA on 2 Jul 2006 15:50 We are using HP Open View and are receiving messages stating: “The IS Mailbox database instance 'SG2-Front-House'Average Delivery time (13228 secs) for last 10 messages is too high (>=10 secs)” We receive an alert approximately 4 times an hour with the seconds ranging anywhere from 100 to 30,000. We had restriction set on a SMTP connector at one point. We removed these to see if this was the cause. Nothing has changed. I have looked online, but can’t find much information as to what might cause this. One theory I was leaning towards was the fact that we have some users with rather large mailboxes (>3GB). We have approximately 200 active users and 30 fall into the <3GB category. Would this cause this alert? What should a standard time be?
From: Nick Gillott on 2 Jul 2006 16:04 Should be a lot less than that. 3GB is not a big mailbox. What is the mail store size? Can you detail priv.edb and priv.stm sizes. Also spindle details - how many disks make up each volume and what are on the volumes in terms of OS, Apps, log files and stores.

My personal opinion is that the partitioning is the problem. Check perfmon for disk writes per sec. But first run ExBPA against it (www.exbpa.com) How much RAM?

6 disks Volume 1 is a two disk RAID 1+0 36GB Ultra3 SCSI 15K Volume 2 is a four disk RAID 5 (3 active, 1 hot spare) 142GB Ultra3 SCSI 15k 4 GB RAM I have previously ran BPA and it gave me no critical errors and only suggested setting mailbox size threhholds because there are non now. Avg. Disck sec/Write Volume 1 = 5 Avg. Disck sec/Write Volume 2 = 10 "Nick Gillott" wrote: > 6 disks > Volume 1 is RAID1+0 so is that 4 of the disks? > Volume 2 is RAID 5 over 4 disks. > > I'd guess that they are all 73GB disks. > > My personal opinion is that the partitioning is the problem.
