Hi all!
This is my first thread here, I hope to find some solution or just an idea and to be able to give help too early!

Well, I'll try to explain my problem:

I've a joomla site running on two server (xeon2,8G, just 512MB ram).
The web live on a server (WEBNODE) and mysql on another (DBNODE).
We receive about 10000 visit for days and there are always 150/200 user connected.

.................Visit - Page - Hit - Traffic
15 Dic 2008 8409 37196 582646 3.13 GB
16 Dic 2008 10758 50285 753278 3.88 GB
17 Dic 2008 3777 19680 253222 1.34 GB

Configuration:
WEBNODE: apache-1.3.41, Joomla 1.0.13b (with eaccelerator), php4-4.4.8. (it's NFS Server too...)
DBNODE: mysql-client-5.1.24_1, apache-1.3.41


Sometimes the site in not available, the server become slow in shell too, so I need to restart apache on WEBNODE.


Here some error encoutered in the log:

On WEBNODE:

[error] [client 87.24.168.141 [note: the IP repeated request a lot of times]] File does not exist: [url]

server reached MaxClients setting, consider raising the MaxClients setting [note: MaxClients = 150 on httpd.conf]


On DBNODE

A lot of:
suhosin[42301]: ALERT - canary mismatch on efree() - heap overflow or double efree detected (attacker '192.168.0.5 [note: this is our lan gateway, so internal access])', file '/usr/local/www/cluster.siciliaonline.it/includes/joomla.php', line 6194)



I thought it was a memory problem...
In the php.ini I increase Memory_limit to 256MB...

Any ideas?

Grazie 1000!

does not look like a memory error, if your site is liable to get more than 150 concurrent users, which for the traffic stats it looks like it does, you may want to up the MaxClients in httpd.conf

<IfModule worker.c>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>

see if that helps with the stability.
