Well, no stability problems here, running for days now without any lockup. I asked a question couple of days ago, concerning how to unpause transmission 1.33. Today I found the solution (I think).
The command is:
transmission-remote -n username:password -tall -s
If this is used as a cron job, all torrents will be resumed automatically at the time you scheduled it. The switch -n username:password is only necessary if you need to login to access transmission, the switch -s means start tall (all torrents).
For me (a noob) it took awhile to figure it out, possibly someone else will find it usefull too
