I saw top occasionally displaying 9999% CPU usage for a process. The first few times it was amarokapp, this last time it was kontact. Both applications were basically idle. The "cc1" is a kernel compile (rc9 + CFS :-).
I cannot remember seeing this before, but as I also don't run top that frequently I cannot be sure its a recent regression. $ uname -a Linux faramir 2.6.23-rc9 #1 SMP Tue Oct 2 11:16:15 CEST 2007 x86_64 GNU/Linux top - 14:28:27 up 38 min, 1 user, load average: 1.12, 0.67, 0.32 Tasks: 128 total, 2 running, 126 sleeping, 0 stopped, 0 zombie Cpu(s): 32.0%us, 15.7%sy, 0.0%ni, 43.8%id, 8.5%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2054476k total, 998460k used, 1056016k free, 95284k buffers Swap: 979924k total, 0k used, 979924k free, 485804k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5269 fjp 20 0 441m 58m 32m S 9999 2.9 0:16.34 kontact ^^^^ 8272 fjp 20 0 5952 468 208 S 3 0.0 0:04.62 faked-sysv 3666 fjp 20 0 25268 2036 884 S 2 0.1 0:03.30 famd 26530 fjp 20 0 20932 6292 1568 R 2 0.3 0:00.06 cc1 5124 fjp 20 0 210m 26m 19m S 1 1.3 0:09.18 kicker 17012 fjp 20 0 19016 1252 916 R 1 0.1 0:00.34 top 5159 fjp 20 0 508m 54m 30m S 0 2.7 0:12.67 amarokapp - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
