We solved this exact problem by reducing BUFPOOLSIZE in dsmserv.opt. It was set very high, causing TSM to (apparently) pin that much memory for its own use - then the OS didn't have enough. Symptoms: high paging, rotten TSM performance, admin sessions took minutes to connect.
Recommend using SELFTUNEBUFPSIZE. (If you already are, then this advice won't help of course.)
