rsync: read error: Connection reset by peer and - writefd_unbuffered failed

Hello, i386 Platform; FreeBSD v. 7.2 O/S I am experiencing repeated rsync failures, rsyncing from a remote site to which I have no access. >From the client side I can run truss to collect system calls truss -faedD -o truss.out -s 64 /usr/local/bin/rsync -avvv --contimeout=1200 --port=33444 ftp.ww

"writefd_unbuffered failed to write 4092 bytes to socket"

I'm attempting to maintain a mirror of a remote database, ~ 66Gb on a FreeBSD platform. I do not have direct access to the database except by rsync, anon. ftp etc. I'm running rsync nightly from crontab, with the cmd /usr/local/bin/rsync -avvv --port=33444 ftp.filesource.org::ftp . >> rsynclog ge
