Swapping 1MB doesn't seem excessive to me. Are you actually seeing performance problems or are the remnants of this bug mostly cosmetic ? This is just something to watch. Right now it is cosmetic. I have this and another box i use. The other is a samba server. I can load it up and see if the swapping goes wacky. The swap usage is going up..albeit much more slowly than before the
errata. This is for the p-4 mentioned previously:
15:24:28 up 2 days, 5:21, 1 user, load average: 0.20, 0.11, 0.03
49 processes: 47 sleeping, 2 running, 0 zombie, 0 stopped
CPU states: cpu user nice system irq softirq iowait idle
total 14.8% 0.0% 0.0% 1.4% 0.4% 0.0% 83.4%
Mem: 382472k av, 377460k used, 5012k free, 0k shrd,
49564k buff
288388k actv, 54068k in_d, 7748k in_c
Swap: 522072k av, 5628k used, 516444k free
221168k cached
ok never mind the swap is now down to 212k. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.3) Gecko/20040910 Description of problem: After installing the U4 updated kernel swapping is still present after 24 hours of use. This is a low load counter-strike and teamspeak server. Cpu usage never goes above 10% except for webmin sessions. as per the url linking to the closed bug this bug is not yet resolved. I have used the echo command noted in the closed bug but some minor swapping is still occurring. This is a p-4 1.4 ghz machine with 384 megs of ram.
