Hi all



I am running a routine that reads data from a dos file extracts a key value and check if record exists on OI file.  If it does I null attribute 3 and write it back.  Each record is 4 attributes in length.



After processing almost 85% of the dos file I get the following error:



OENGINE caused an invalid page fault in

module LHCLNT.DLL at 0167:21004a85.

When I manage to restart OI I check the OI file for GFE's and there is an error on frame 0 which is 'free frame list is not sorted'.



Running routine on local copy of routine.



Started from scratch a few times and it falls over in the same place each time.

<QUOTE>Micheal,



Ouch!  Looks like a bug in the depths of Linear Hash.



Is there any chance you could create an RDK with everything required to reproduce this bug?  I'd really like to get to the bottom of this one.

sorry for delay but been on the road.



I tried running the routine against data from 6 months ago.  It is the same file but a copy from 6 months ago and it ran fine.



I then compressed the current file, which had the error, in database manager and ran the routine again it worked file this time.



Does that change your view of what may have caused the error



Cheers

<QUOTE>Michael,



  Apparently there is a bug in LH that will GPF while processing your "corrupted" file, which doesn't surprise me.  If after compressing the file, which essentially rebuilds it, everything is fine, I will stop worrying about it.



Cheers!

<QUOTE>Neat. Compress the table and the bug gets squashed. I think I must compress my SYSPROCS right away.
