    I'm also working on this with IBM - ANY ideas welcome.

    We upgraded a large, busy system from 4.3.3 to 5.2ML3 about two weeks
    ago. Now, on 4 separate occasions, we have received

     IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION
     684A365B 0729000704 U U SYSPFS FILE SYSTEM CORRUPTION
     ...
     Detail Data
     FILE NAME
     xix_lookup.c
     LINE NO.
              322
     MAJOR/MINOR DEVICE NUMBER
     002E 0001 <-- /var/spool/mail

    We run qmail. This filesystem is on a LV which is on SSA disks using SSA
    RAID. It's big - about 150GB. This always happens while the system is
    under heavy load.

    This has obviously been quite a panic, and has kept me up all night
    several nights waiting for downtime so I can boot into single user mode
    and run fsck on it. Mostly, fsck does not find any problems.

    IBM has had me updating bos.rte.<several things> to 5.2.0.40, and
    updating the microcode in the SSA adapter cards to the latest, to no
    avail.

    Anybody seen this before or have any idea what is going on?
