DS 1.2.2 (794)
SLES11 SP1 VM 12 Gig Ram

This morning one of my servers (180 users) had the Mobility connector crash. Upon investigation the server ran out of memory (6gig no SWAP)
I increased the available memory to 12 gig and rebooted. In 3 hours the server has consumed 6 gig of memory and rising. My other servers are at the top of the memory as well, however they do have swap space and no issues reported yet.
This is the first time I have seen this, and I just upgraded to the latest version about a week ago. My Python threads are by far the largest consumer of memory (TOP will show Python at up to 25% of memory)

Any one else seen this?
Any thing I can do to nail it down?
