I've noticed a lot of crashes lately too. Only UO, ICQ, UOA, and Ventrillo are running.
Not only that, the new client seems to have a HUGE memory leak. After 5 minutes of running around I check my resource usage. Processor use is at 40% (on a 1.2 ghz) and memory usage is at 150Kb. That is WAY too much, as when i start its at 10% and 13Kb. -releasemem works for a SHORT period (meaning under 20 seconds).
I reduced the cache size in my config file, that has helped some.
The UO client has *almost* forced me into running a script to type "-releasemem" every 15 seconds!!!!!!
