1051.0. "%%% HELP %%% OSF 4.0A - ADVFS INTERNAL ERROR: dealloc_bits_page: can't clear a bit twice!" by NNTPD::"faidherb@tsc.bro.dec.com" (Thierry FAIDHERBE) Thu Apr 24 1997 06:35

Hi,

One of my customer called yerterday for a system crash.

When analysing, I saw that was one OSF 4.0A - ADVFS INTERNAL ERROR:
dealloc_bits_page: 
can't clear a bit twice! crash.

I found two IPMT cases for that problem but both are closed without solution.

NO patches, solution or workaround for that problem have been provided

I put my crash-data file.

Can someone take a look or inform me if USengineering is working on it or if
I must open a new IPMT case.



Thanks for quickly help .... 



Kind Regards,
