Hi all, I have a Penryn MacBook Pro 2.4GHz, with 2GB of RAM running OS X Leopard 10.5.2. I usually leave my laptop on or at sleep for days, and it usually works. However, on one random day, at one random time, every 4 seconds kernel_task gets 140 or so CPU cycles and completely locks the system from use (mouse stops moving, no activity) for 10 seconds or so. This goes on in a cycle. Before this happens, I see that the syslogd process gains a lot (50+) of CPU, and then it just crashes. Not sure what is going on. Thanks!
