Hello,

Hi, I will give more details about my problem. There are about 1000
simultaneous
conections. The server has 256Mo of RAM. Pound balance php files to apache and
there are about 30 apache chields running (20Mo each) in the task list. Pound
balance gif/jpg and other static files to a thttpd server.
I have this config :
Server 60
Client 15
Alive 5

Since I have increased the Server param to 60 seconds it seems to be better but
I'm still having ""Error 503 - The service is not available" from time to time.
And the errors can be returned for serving php files (apache) as well as
serving
static files (thttpd).

This my hypothese : Pound decide that apache or thttpd are down from time to
time and I have those errors. But the servers are not down.

Could it be a problem of bandwidth limit reached? How can I see that? Do you
think I can improve this by installing a php opcode cache accelerator? If it's
a bandwidth limit, I think it wont do anything, right?

I'm not sure the problems comes from pound but the error page is coming from
pound. If somebody can help me thanks.

Hi,
Sorry I don't want to spam this mailing list but I have another question to ask
on the same topic. I read in the man than setting Alive to 0 was cancelling the
functionnality to test servers availability. I put "Alive 0" in my config file,
and pound didn't want to restart. I had to delete the line in my config file in
order to make pound restart.
Is there a possibility to cancel this functionnality to see if the server react
better under overload?
Thanks!

Thanks
If I understand correctly, pound decides a back-end server is down when it
doesn't receive an answer from this server after x seconds, x being the
parameter "Server x" in the config file?
