Next - OIT = 776458, i.e. every snapshot (concurrency) transaction requires ~192KB for private TIP snapshot. Also, at transaction start, it should read 48 TIP pages to build that private TIP snapshot.

You should sweep database fromt time to time to "unstuck" OIT.

Look also at Next - OAT = 106768, it show that there are long running transaction(s) present. Look at MON$TRANSACTION for tx 55360946 to see what is it and fix application which was started it.

Good luck,
