Re: Alpha crashing

Mulder,

what is your hardware, and what software versions are you using (especially DECnet and OpenVMS)?

Try;

$ show sys/full/noproc

$ prod show prod/full DECNET*

$ prod show prod/full VMS

Please post the output in a text attachment.

Many thanks,

Duncan

Re: Alpha crashing

Also look in the SYS$ERRORLOG directory for a file with a name starting with CLUE and dated for the crash. Post that if found.

Re: Alpha crashing

hi,

there is certainly ecos for v7.3-1 x25 that addressed a number of bugcheck issues :-

http://www11.itrc.hp.com/service/patch/patchDetail.do?patchid=AXP_X25ECO03-V73X&sel={openvms:alpha:7.3-1,}&BC=main|search|

as well as further ecos for decnet-osi that you should be looking to put on first

http://www11.itrc.hp.com/service/patch/patchDetail.do?patchid=AXP_DNVOSIECO03-V731&sel={openvms:alpha:7.3-1,}&BC=main|search|

if you've a support contract with hp and place a call ,as you probably know the first thing they'll ask you to do is get current with patches !

fwiw

Re: Alpha crashing

Hi,

please attach the CLUE file from this crash to your next reply. You'll find that file on CLUE$COLLECT:CLUE$node_ddmmyy_hhmm.LIS on OpenVMS Alpha V6.2 or higher.

Re: Alpha crashing

Sorry, couldn't download the .ZIP file with IE, but it worked with Mozilla on OpenVMS.

This crash in GAP_DISCONNECT_SESSION_C+C8 is a 'popular' problem footprint. You're running X.25 V1.6 without patches. This problem is supposed to be fixed with V1.6 ECO 1 or higher.

Re: Alpha crashing

Thanks to all for responding quickly...

patching is not an option at least for now...any work around ?

Also, what does this means :

GAP_DISCONNECT_SESSION_C+000C8

Thanks

Re: Alpha crashing

The crash is an invalid exception and happens at the instruction LDL R16,#X0060(R16), because the contentsw of R16 is 0 (ZERO), leading to an invalid access to virtual address 00000060.

This insturction is inside the module X25$ACCESS.EXE and the routine name and offset inside this module is symbolized by SDA as GAP_DISCONNECT_SESSION_C+000C8.

There is NO workaround - except NOT using X.25 - other than installing the current X.25 V1.6 ECO.

Re: Alpha crashing

If you can't upgrade, find out what changed and do a roll back of that.
