I've seen a few posts about this. I had no problems with transmission until I started playing with the uid/gid of my zfs volumes. Turns out I accidentally ran "chown -r" on too high a directory and clobbered the permissions in my jail. I could start torrents but they would stop with weird, non-specific "Permission Denied" errors. The most tell-tale one was "Unable to save resume file: Permission denied".
Transmission lives under /usr/pbi/transmission-amd64 in the jail's root directory. It seems to store resume data along with other internal state under/usr/pbi/transmission-amd64/etc/transmission/home/. If it can't write to to these, bad things happen.
This had nothing to do with umask issues as other posts had suggested. I guess this could happen if you tried to run your jail on a filesystem that doesn't support proper posix permissions. On those systems, setting chmod 777 would probably let transmission write to it's config files but I'd seriously stop and question the quality/security of your setup if you have to resort to such measures.
