[mythtv] Backend process dies at 4GB file limit?

Thu Jan 19 03:30:17 UTC 2006

Are you interested in this scenario:

Backend saves files to FAT32 partition.
Backend tries to exceed 4GB (or there abouts) while unattended.
Backend dies with error "File size limit exceeded" emitted by OS.

Backend's last message prior to dying was:
"TFW: safe_swite() funky usleep"
(message comes from ThreadedFileWriter.cpp )

Buzz.

P.S. Before you tell me "FAT32 is a bad, naughty, unsupported filesystem"..
tell me another filesystem that works under both MS Windows and linux,
reliably, and I'll happily change (I'm waiting in anticipation of native
ext2/3 windows drivers or NTFS write support in the kernel - it's a long
wait)

Last couple of screenfulls of the Backend log (-v all) follows:
