My system beachballed for the second time this week. So, this time around instead of restarting the system I checked out Activity Monitor to see if I can spot the trouble. Mac Mail was eating up 6GB of RAM. Could tell me if there's a solution to this problem - it is definitely not normal is it? I also observed that the RAM amount was going on increasing - after free memory was finished it went on to consume the inactive memory as well. Please let me know if I can solve this issue.
