I've been getting a lot of timeout/Internal Server Errors and slow load times and a few other strange behavior problems on a site that's still in development (so I'm the only one on the DB). Any suggestions on what could be causing this?

Is it cheap cheap hosting? It could be an overloaded server or a low memory limit.

Do the error occur randomly or just on certain pages or during certain actions or operations?

Hosted on aplus.net. Been with them for a while and haven't had a lot of problems yet. If you think I need to check this out further, however,I will.

The one area I'm really having problems is with form submissions which use a different MySQL db on the same server and then hands it back off to a landing page that's also php. My initial tests are that the form submission that are on HTML pages aren't having a problem when I've tested them but I need to do more tests. The site has been in development for a LONG time and form submissions on php pages that were created a while back worked just fine up until recently.

As I've been working on the site almost non-stop for the past few days I've also noticed long load times and time outs both in the application and on my pages- many of which were written months ago and performed fine at the time. That's why I suspect it's not the Form Submission db.

I did upgrade a couple of weeks ago before starting work on the site again. Earlier today I just completed another upgrade just in case there was a patch fix although the problems remain. I also went back to both applications and made sure the chmods were set to 777 for all the files that needed write permissions,

If you can reproduce the problem then it's probably something in the code of the page and you could investigate further to try and track it down.

But if it's seemingly random then it's may be other users or websites on the server that are slowing it down. The way to check that would be with the unix command 'top' from the command line to check the CPU and memory usage.

Is it random or can you reproduce it? Also, does it happen more often at certain times of the day? I've seen a few hosts that get really slow in the evening as general internet usage goes up (and other sites on the same server get hit more).

Aplus tells me that there's a global limit of 32mb for PHP memory. Could that be a problem?

Hi

I am thinking that's the problem too. I'll double check with Dave when he gets in but I would get back in touch with your host and ask them what options you have for getting that increased. Perhaps they have a different plan you could switch to.

Keep us up to date :).

Yeah, after posting that I started thinking "global" means 32mb for every single php site on the shared server. I have no idea of how many sites are on a shared box but if it's in the hundreds and half of them run php that's probably not a lot.

The site is currently on their second highest plan for a shared box. When I upgraded one of my other sites to their highest plan the server didn't change so I'm guessing I should probably check into Go Daddy or some other hosting provider to see what they offer.

Sid,

Also check if you can find the error logs. Sometimes those give some clues as to why 500 server errors occurred.

Double blarg .. not godaddy!

Try HostGator http://secure.hostgator.com/cgi-bin/affiliates/clickthru.cgi?id=Jenolan their php settings are great even on their most trivial plan. I swapped from my own dedicated system to HG that's how good they are!
