I believe we've been seeing this problem as well. One night in the busiest backup period, I issued a "q actlog begint=now-00:30", and got no results back but an error.
I started dsmadmc -console on that server, and could see that the console output was most of an hour behind. (And the console output was scrolling so fast that it could barely be read.) In that case, I think we determined that SQL LiteSpeed was set to some rediculously small transaction size, and this was causing way too many actlog entries. I think I also noted that the session number incremented by something like 100,000 in an hour. Asking the users of SQL LiteSpeed to make some changes was enough to rememdy this problem, although we continue to fight with the logs getting full.

Here is a small follow up on my PMR about the recovery log utilization. I'm at TSM level 2, still trying to convince them that there is something broken in the TSM server code. To convince them, I have changed the logmode to normal on one of my servers. I created a graph (through TSMManager) which shows the recovery log utilization during last night's client backup window and is doesn't differ much from the night before, with logmode rollforward. When running in normal mode, TSM should only use the recovery log for uncommitted transactions, so utilization should be very low. My log is 12 Gb and the backuptrigger value (75%) was still hit twice! This clearly shows that there is something wrong with TSM, let's hope I can convince Level 2 too, so my case gets forwarded to the lab. I'll keep you guys posted!
