[users@httpd] server busy
hello,
we get a message in apache log-file that the server is to busy and that we
should rise the amount:
[Sat Aug 5 17:08:53 2006] [info] server seems busy, (you may need to
increase StartServers, or Min/MaxSpareServers), spawning 8 children, there
are 2 idle, and 12 total children
At the moment we have following values:
StartServers 5
MinSpareServers 3
MaxSpareServers 5
Could anybody please tell us which values we should use?
Thank you
Mike Roland

The apache error-log says nothing.
So I think we should leave the values like they are.

Those have nothing to do with apache, although they do seem to suggest
general resource problems on your system. Try the apache error_log.

That is a miniscule quantity, so your settings for these directives
are completely unimportant.

We had on Saturday 600 visitors for the whole day all sites together.

Those are still very low for a busy sight. They are fine for a site
that doesn't expect to see many simultaneous accesses.

thank you Joshua,
I tried to mount the numbers, but I fear this was too high,
cause the apache server could not be started anymore.
Could you give me an idea about the amount please.
As I told you we have at the moment:
(original values)
StartServers 5
MinSpareServers 3
MaxSpareServers 5
MaxClients 100 (50 was the original value)
If we change the values to:
StartServers 10
MinSpareServers 6
MaxSpareServers 10
say double the values, is this what you would propose?
Thanks for a tip.

The message in the error log is just informational. It only means
your server will be slightly slower responding to load changes; no big
deal.
To get rid of it, you should increase all three of those numbers. A
good number for StartServers is your average number of simultaneous
clients. MinSpareServers should be big enough to absorbe your typical
changes in load. MaxSpareServers should be somewhat bigger than
MinSpareServers.
You can use the server-status handler of mod_status to observe
activity on your server to fine tune these settings.
