-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I have a server resource problem, and need to take immediate action. I have very fast disk available to this e-mail server: a 3-plex FC mirror served by a SAN.
But, the server is becoming CPU bound. I believe that I have made all the optimizations that I can make in qpopper: server-mode, temp-drop-dir (in memory based FS), disable-check-pw-max, and disable-any-kerberos-principal. I would like to move the qpopper processes from my monolithic email server (mail, it is a Sun E3500 6Gb Ram, 6 processor) to an adjacent server to offload processing. I would accomplish this by manipulating network traffic with a Level 2 switch. The problem of doing this is of course file access to the spool directory. Everything that I have read is that Solaris 8 NFS (NFS 3) doesn't properly safeguard against file corruption, and could result in silently lost e-mail. Is there a way that I can overcome this problem, and still off load my processing to another server? I do not currently have a Veritas Cluster ( or similar ) license. Although this may be the route I proceed in the future, I need to buy some time to get me there. Could you please offer suggestions / opinions regarding this situation? The impacted group (of the server's performance problems) are out webmail clients, who see diminished throughput ( correlated to the server's load average being high ) when the server is busy. This group uses IMAP, but is a high usage group. I am looking to offload the POP3 traffic for two reasons. First, it seems to be simpler to address that offloading IMAP. Second, large mailbox users ( 50+ MB ) appear to spike CPU utilization on the mail server. Thank you in advance for your response.
