Ok a quick update:
I've read all the files and, from syslog, I can see when the crash happens
Code:

Any idea of what is going on?
I really want to understand how the server crashed, so to avoid another crash for the same reason...
thanks
Michele

Nothing strange there, could it just be high load that made server crash? Do you have any monitoring software that monitors load and than email if the load is over 1.

What do you mean "it is over 1" ?

No anyway, I've not a monitor script yet... do you suggest me a specific software or I need to write a kind of perl or bash script that will monitor the server load, the memory usage, etc...?
In this case, can I get the value from the ISPConfig database? (the values shown in "show server load" for example...

Thanks
Michele

I have Nagios installed that monitors every server and service. Nagios is installed on separate server and it's not in the same datacenter as rest of my servers.

Nagios can monitor everything that can be monitored

He is taling abou the server load. You see the server load when you execute the command "uptime" or use the "top" command.

Hi till,
thanks for the explaination...
I've this as result of uptime command:

SVR1: 13:23:44 up 2 days, 36 min, 1 user, load average: 1.07, 1.16, 0.95

SRV2: 13:23:35 up 2 days, 18:36, 1 user, load average: 1.47, 1.46, 1.19

Is that fine?

Thanks
Michele

Yes, thats fine. If you get loads > 10 then your server will start to react sluggish.

Ok then it's fine, because the max value of server load that I've noticed was 3... from your experiece, with a server Dual-Core AMD Opteron(tm) Processor 1216 HE and 4GB Ram, how many emails I can manage? (I mean, how many emails for minute as an average).
I know that it's difficult to say, but just more or less...

Anyway I'm still investigating the cause of the crash... with not so many progresses...
