-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello! My friend and I have both been having issues regarding unexplained load on our machines. His was the culprit today and I finally decided to send it in to the list. Below is some output which shows the 2.00 load average (dual CPU) and the lack of processes to explain it. I think it's probably something in the kernel taking the CPU, however I know of no way to check. I had the same problems on my machine about 5 days ago (4.3-RC) except it was 1.00 (single processor) instead. I am assuming that there are others having this same problem out there and would love to get an answer to this. (Or perhaps it's been fixed? It's very sporadic(sp?)) I also checked for trojaned binaries in case someone had put a rootkit on the machine but could find no traces of one present. I even checked /proc/*/status manually and they matched up with what ps was reporting. I am doubting this is a security issue and assuming that again, there is something in the kernel causing this load. Any help would appreciated. Thanks in advance, - -Jason DiCioccio - ---------------------------------------------------------------------- - -------- spritle% uptime (~) 4:10PM up 2 days, 23:57, 2 users, load averages: 2.00,
