My raq3 currently has 256mb or ram. Would upgrading the memory to 512mb help correct this problem for a quick fix? I am waiting to get my hands on a raq 550, but it is not yet availiable by my web hosting company (4webspace).
What should I do? Remember, you are dealing with a technical idiot.
Before giving up your money, you really need to know what is actually causing the bottleneck on your server. Ultimately, throwing hardware at a problem can make it go away, but it might all be caused by a CGI script that you can do without or replace.
Do you know how to TELNET/SSH into your server?
If you do, then the next time you get the email, login to your server via TELNET or SSH and issue the following command:
This will give you a dynamic display of what is currently running on your server. If the 3 values follow "load average:" are low (<2) then you've missed the problem and need to try again when you next get the problem report. If they're higher than 2 then you might get some idea of where the problem is.
If you now look down at the long list of processes that are running, what processes are showing at/near the top of the list?
If you do get a list of things that you think might be showing the problem (i.e. the 3 load average numbers are high, >2) then copy the whole top display and paste it into this thread and we can help you pick it apart and see if we can identify where the problem actually is.
There's often a lot more to it than just this, but it's a good start.
