IMv9 + IMv10
We are seeing lag and users getting disconnected on the old IM 9 servers.
We had 5 IM 9 systems running both mux and backend and one pair of IM 10 systems: one mux and one backend.
We ran in that configuration with no problems for about a week.
Today we took down one of the IM 9 systems (leaving 4 IM 9 systems running both mux and backend) and brought up a new pair of IM 10 systems, making 2 IM 10 frontends, each talking only to its respective IM 10 backend.
At about the time we brought up the new backend, the IM 9 backends started doing full garbage collection(GC) every 4 or 5 minutes.
Upgraded IM 9 to IM 10.
