Hello Managers,

I'm having no end of troubles with our ES40 which is running 4.0f with
latest patches. We've isolated our rebooting problem to trying to
delete a certain directory. It's on a HSZ70 RAID, and mounted as a
178GB AdvFs partition and connected locally to our ES40.

On a certain directory, there are a few other large directories, seems
like if there is an attempt to remove any of them it will result in the
machine rebooting. I can touch a file and remove it in that directory,
but I can't remove already existing files within that directory.

In the crash dump file, I see the panic_string is "bs_frag_dealloc:
pinpg (1) failed\n N1 = -1035"

I also see ADVFS EXCEPTION


Here's the /etc/sysconfigtab

proc:
        max-per-proc-address-space = 38441425310
        max-per-proc-data-size = 38441425310
        max-per-proc-stack-size = 134217728
        maxusers = 2048
        per-proc-address-space = 38441425310

vm:
        ubc-maxpercent = 90
        vm-maxvas = 38441425310

vfs:
        bufcache = 1

This machine has 16 GB of main memory, and about 20 GB more of swap.
Which is why those numbers are so high.

crash-dump file is available upon request. Email me if something is not
clear.

TIA,

Kevin
