Dbcache disable - does it help server crashes?

We have a 2 server Domino cluster. No load balancing (the second is for failover only - with the excepton of 2 users).

Our primary server has been plagued with crashes for months.

IBM techs have offered no solution to date.

We had 2 crashes yesterday. Both appear to be nrouter.

Was wondering if anyone has had any luck with dbcache disable helping with server crashes.

I just turned off dbcache this morning after being made aware of the second crash yesterday.

(Happened after I left)

Some things we have put into place to try to solve:

  • Upgraded to 6.5.3 FP1

  • Moved primary data to different hardware (with the exception of the SAN FiberChannel card - this card was moved to different hardware too)

  • Reloaded Domino and put software/application files on C: and Data directory on SAN (previously, both were on SAN)

  • Removed the server from our Belkin KVM switch

(Installed keyboard, video, and mouse directly to server)

  • Removed .ini settings to write to debug file and went with console logging instead (for some reason, there were 2 seperate entries in the ini to write debug info to 2 seperate files - removed both lines)

  • Removed much of the workload from this server by placing another Domino box “upstream” to handle SMTP mail from CA eTrust Content Filter/Spam Filter.

Nothing thus far as helped.

What is next in line for us to try:

  • Moving primary Domino to brand new IBM hardware (Wintel,2003) with brand new QLogic SAN Fibre Channel card (moving this tonight)

  • Configure transactional logging to minimize downtime due to consistency checks

  • Removing inbound iNotes and passthru connections from this box (moving them to the upstream server instead)

If nothing listed here works, and we can’t get additional suggestions, I am quite sure that my executives will force me to move to a different email platform.

Any suggestions (as strange as they may sound) are appreciated !!!

Thanks,
