Hi,

What was the cmd line used? Is your file > 2GB?

IIRC linux send a SIGXFZ for vfat fs, even if the file is open with O_LARGEFILE. You have to add a 'signal(SIGXFSZ , SIG_IGN);' there's none in ssh.

This sounds plausible, although I'm not sure that simply ignoring the signal is the right fix.

I get something very similiar (termination due to signal 25, SIGXFSZ) when letting "cat" write into a FAT32 system (in my case "cat /dev/video0 > foo.mpg"). Tried patching cat to no avail, which actually makes sense since it's the shell which is writing into the file. I tried zsh and bash...

Surely all the tools can't be changed to ignore SIGXFSZ, the right fix is in the vfat code of the linux kernel, isn't it?

 As a matter of fact my memories were about linux 2.4, I had the
problem with netatalk.

In my understanding, after a quick look at linux 2.6 source code, it's
by default for all file systems write, cf. mm/filemap.c.

On the other hand SIGXFSZ is sent when files ulimit is reached so
maybe tools should
deal with it.
