We had a recovery log pinning problem and the log was growing since last
4 days and currently is at 72% util...
TSM Server 5.3.3.0 running on z/OS.
Below is the SHOW LOGPINNED output:

(snip)

It looks like you're currently running a database backup; that should clear the 
log unless the pin is stubborn.

If the db backup doesn't clear up your problem, you may want to consider taking 
the TSM service/process down and then restarting it.

Has this happened before?
