Any advice would help
Hi everyone. I must admit up front that I am not very strong when it comes to Linux. I am actually a Windows guy, but don't let that count against me.
I work for a very small company so we do not have a Server/Linux Admin on staff. Most of our needs have been handled by our WebHost. We have started running into a problem and I can't seem to figure out what it is and I was hoping someone could point me in the right direction.
My company is webbased. We have one server that runs Apache and PHP. We have a secondary server that is used strictly for MySQL. We know that our PHP code is not as fine tuned as we would like it to be, but overall it is pretty solid. To ensure that it is we are in the process of installing Zend Platform to help catch some bottlenecks and such. The webserver is running RedHat, not exactly sure of which version but I know it is pretty current. I could get the exact info if it is needed. It is a Dell PowerEdge 1425 with 2 Xeon 3.2Ghz Processors, 2GB RAM and 2 80GB mirrored Hard Drives. Our server load has been skyrocketing lately. We have had an increased traffic level so it is understandable to a point. When I view top it seems to run on average from a .2 to around a 1.8. But it does get up around a 4 to an 8 quote a bit. So far today it is has skyrocketed to about 210 before Apache crashes and restarts. It has done this 4 times today. On average over the past 2 weeks it does this about 4 to 5 times a day. I know the code isn't perfect, but this seems pretty crazy to me. Zend Platform will be installed within the next few days so that will shed some light on the coding issues, but I guess I'm worried that something else might be going on as well.
If anyone could point me in the right direction to find out what is going on I would appreciate it. Again, I'm not a Linux Admin so my knowledge is pretty sparse as to how to go about locating the problem. Thanks in advance.

uptime
UPTIME(1) User Commands UPTIME(1)
NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime [options]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
OPTIONS
-p, --pretty
show uptime in pretty format
-h, --help
display this help text
-s, --since
system up since, in yyyy-mm-dd HH:MM:SS format
-V, --version
display version information and exit
FILES
/var/run/utmp
information about who is currently logged on
