hi Gregg
Log a tac case for sure, you can help speed up the resolution by collecting some pertinant info such as:
1. does the leak increase linearly with time ?
2. does the leak only happen when clients are connected ?
3. does it happen on the VC or non VC or all ?
Also collect the tech-support dump (ensuring to target an affected AP) over say 3 fixed intervals (if the AP reboots within 6 hours, then collect the tech-support dump 3 x 30minutes, but not more frequently) and send that to TAC - it will give the R&D people something to go on.
Most likely with a leak as bad as you describe that it's a regression bug and someone will have probably already found the whoopsie and fixed it, but could also be a sizing issue where someone forgot the smaller ap-103 so may take a TAC case to get R&D onto it.
and then there's always rollback :)
