Hi! all,
My raq3 has benn sending me this mail for the last days.
###################
Over the past fifteen minutes, the CPU has been heavily loaded.
This will result in noticible performace loss. Consider moving some of the
services to other Cobalt servers, or reduce the complexity of the CGI
scripts running on the Cobalt server itself.
1 minute load average: 31.11
5 minute load average: 28.12
15 minute load average: 17.41
The processor is currently 25 degrees Celsius.
The system has been running for 0 days, 21 hours, and 35 minutes.
##############
there are very few cgi-script running on the raq.
I tried to "ps -aux" (I've copied the output below)
but it has not cleared the problem.
Is it possible that the CPU overload is due to
a virtual site that is making 350-400Mb/days transfer over 50000-70000 hits.
I looked at the web.log file.
For all the other virtual sites the cobalt has a log directory with:
ftp.cache.new
ftp.log
...
...
web.cache.new 1Kb
web.log 97 Kb
web.stats 4Kb
For the site making a lot of traffic I see:
ftp.cache.new
...
...
web.log 0byte
web.log.1.gz 1985 Kb
web.cache.new 2789 Kb
web.stats 1796 Kb
When I downloaded the log file from the web based interface i got a 10 Mb
file!
Is it possible that the CPU is overloaded becouse of handling such a big
file?
If not, any idea?
Ciao Grazie
Filiberto
