Online 6.0 & Solaris 2.3: Error building 'sysmaster' database?

We are trying to get Online server 6.0, (6.00.UE1 exactly), going on a Sparc 10 running Solaris 2.3, (with fairly up to date patches - our Jumbo Patch #101318, is up to -45). We have our /etc/system file set up as recommended. We are just trying to get it going with a cooked UFS database, and the learn environment. When we do "oninit -i", it runs and completes. But the online.log says: ---------------------------------------------------------------------- Fri Apr 14 13:05:31 1995 13:05:31 INFORMIX-OnLine Initialized -- Complete Disk Initialized 13:05:32 Checkpoint Completed: duration was 0 seconds 13:05:32 On-Line Mode 13:05:32 Building 'sysmaster' database ... 13:05:33 Error building 'sysmaster' database 13:05:33 See '/tmp/buildsmi.394' ---------------------------------------------------------------------- The buildsmi.394 file says, basically, "Try again." We can manually do a buildsmi: ---------------------------------------------------------------------- 13:38:47 Logical Log 1 Complete 13:39:09 Logical Log 2 Complete ---------------------------------------------------------------------- But then, when we do onmonitor, it says "** WARNING: Network Down **--On-Line-------", and crashes the server: ---------------------------------------------------------------------- 13:40:50 Assert Failed: Internal Error - Segmentation Violation 13:40:50 Who: Thread(5, msc vp 0, 0, 6) 13:40:50 Results: OnLine must abort 13:40:50 Action: Reinitialize shared memory 13:40:50 See Also: 13:40:50 rsdebug.c, line 3251, thread 5, proc id 399, Segmentation Violation. 13:40:50 PANIC: Attempting to bring system down ---------------------------------------------------------------------- So far, we have re-installed the server. Informix support hasn't seen it before. Any one seen it? Or have any ideas? Thanks! Don Don Erway derway@ndc.com NDC Systems 818-358-1871 730 E. Cypress Ave Fax:303-5770 Monrovia, CA, 91016
