FreeAXP - Tru64 V5.1B - frequent crash

Hi,

While trying to run Tru64 V5.1B on FreeAXP (host Windows XP SP3), frequent crash / freeze occurs.

FreeAXP version - 2.0.0.377
Host OS - WinXP SP3 v.3311
Guest OS - OSF1 AXPES40 V5.1 2650 alpha

Configuration:
Memory - 128 MB
Disks -
- SYSDISK - 2 GB RZ73
- DATADISK - 8 GB RZ40L
- SWAPDISK - 1 GB RZ57

Using dedicated physical NIC and card type DE435.

The crashes are random - kernel fault - invalid memory address - or just a console freeze.

Its not predictable and can happen anytime. Today the crash happened twice: first when nothing was going on. Second time a FTP file transfer was in progress. Earlier we have seen the crash while there were some X Windows were open (thru Reflection X) but idle anyways.

Twice the dsk0 (root file system) was corrupted and we had to re-install Tru64. Now I am keeping a backup of all the disk images.

Any help, suggestions will be much appreciated.

Regards, Abhijit.

Hi,

Could you post the crash details please ?

- captured from the console immediately after the panic... or
- captured in /var/adm/messages after the next Tru64 boot ... or
- captured in /var/adm/crash/crash-data.X (if it saved ok) after the next Tru64 boot ...

regards,
John M

Also, you might try using a De500 instead of the De435. It probably won't make any difference, but just in case .... <img src='../images/smiley/wink.gif' alt='smiley'>

John,

1) I did not capture the console messages - so I will post that after next crash - whenever that is.

2) Some parts of the /var/adm/messages:

You can see multiple boots happening - each one after a crash.

3) There no file under /var/adm/crash - will check again once there a crash again.

Thanks,
Abhijit.

OK - Thanks for that update.
Since there is nothing under /var/adm/crash there will be no crash detail in /var/adm/messages either. An empty crash directory means that either there was a problem writing/reading the crash to/from the swap device, or that it wasn't a 'normal' Tru64 Panic ... So the console capture will be the only way forward. For that, please log the /dev/console tty output, or copy/paste it once(if) the next crash occurs.

regards,
John M

Hi,

The system has not crashed since yesterday. But today I got a new problem and this time I captured the console output - same thing is repeated in the /var/adm/messages too.

In the middle of a file transfer (FTP), the data disk (dsk1) became inaccessible.

Machine was alive - but /data (mount point for dsk1h) was not accessible.

ADVFS panic
