Memory leak?

[David Leadbeater]

Hi,

I'm getting an out of memory from brackup when backing up some large  
files to
S3. (Well, not *that* large -- the largest file is 250MB).

This is under Perl 5.6.2 and 5.8.8 (I tried upgrading Perl just  
incase) on FreeBSD 5.2. Using Brackup 1.0.5 installed from FreeBSD  
ports. The box has 1GB RAM.

If I watch the brackup process while it's running it does seem to use  
a lot of memory.. (Around 130MB to 190MB RSS, the VSZ is around 500MB  
but I guess that's just files being mmap()ed)

Eventually it dies with an error like the one below.

It seems to carry on where it left off if I start it again so it's  
fairly easy to work around anyway.

Any ideas?

Thanks,
David
