Encoding large number of files in one go crashes system
I am running Windows XP with Service Pack 2 and the Vorbis 1.0.1 Tools.
When I was trying to run a large batch query converting standard WAV files (14
GB in 255 Files (21 CDs) in a single directory) to Vorbis using OggDropXP
(Quality: 6, no special options), the whole system reproducibly froze (3x) after
approximately 1 GB of source data had been processed.
Suspecting OggDrop, I generated a batch file that individually called oggenc for
each one of the remaining 200 files. Running the batch file in turn reproducibly
led (4x) to a blue screen (IRQL_NOT_LESS_OR_EQUAL variety). The crash once again
occured after about 1 GB of source data.
I have just finished encoding all files by dropping the remaining 100 files into
OggDrop *one CD at a time* without incident.
I do not think that the actual file content has anything to do with the problem,
as the files affected by crashes were all handled without problems when I
subsequently resumed encoding with the exact same file.
My system is stable and I think I can rule out completely unrelated causes for
the crashes, which occurred exactly, and only, when I used OggDrop/OggEnc. I had
extensively used OggDrop before without any problems, but only for one CD at a
time.
Of course, it is possible or even probable that the actual fault does not lie
with OggEnc/OggDrop, but the Windows Kernel/Explorer and was merely triggered
through the interaction with OggEnc. Still, I find my system's behavior quite
bizarre. While I could at least in principle imagine how a large number of files
could crash OggDrop, I have no idea why OggEnc should be affected by being run
50 times in a row.
I know this bug report is only partially helpful - if I can reproduce the blue
screen one more time, I will add the detailed information (especially which
module caused it).
