I think that there is a kind of memory leak concerned with system.server proccess. It uses lots of ram with normal using of phone, it's like after a few hours of using Milestone to sms, mail and talking, memory used by this proccess raises to about 55mb. I have checked CM7 and HONO CM7 and they keep this proccess at under 30mb. TO check this write procrank in terminal emulator, the USS value. Please check this out. Sorry for my english
