Re: Load balancing question

Hello,

Everything is Windows2003 Server.

After the load we cannot load pages either through apache or by contacting 

tomcat directly.

I beleive you are on the right path tho, about connections not getting 

released, thats what I figure it is too but I do not know how to fix it.

Thanks,
James

We also have the problem of once the load stops, the sites are still down 

but Apache/tomcats still seem to be running fine.  A restart of 

either(not even both) fixes the sites.

A guess

 Your apache server is not releasing connections.  If you are running 

linux, type  "netstat -vat" into a terminal on your apache machine, before 

and after you hit your server.  See if the connections are being released.

You could also try typing "ps -e | grep "httpd"" to see how many apache 

processes are being run before/after.  Look in the apache error log, etc. 

You might find a clue like "MaxClients reached"

Question

Are you able to log into all your tomcats(through port 8080) independent 

of apache and get served requests?  Can you log onto apache and get a 

statically served page?

Cheers
AFrieze
