Error 508 / 503 - Resource Limit Reached
To help maintain the stability of servers and keep websites fast, UltraWebHosting has resource limits on our shared hosting and reseller plans. Our servers allow a hefty amount of processing and memory power but do not allow a shared hosting plan to take more than 5% of a processor on a server. This ensures there are always enough resources to keep every website running fast and protects other sites on a server from being brought down by a single website.
You can check your resource usage inside cPanel, going to Logs -> Resource usage. If you hit any limits in the last 24 hours, there will be a summary on this page. You can also view charts and graphs by clicking on the details link.
How can you reduce resource usage?
You can try disabling plugins or scripts which are not necessary, disabling any special features, add a bad bot blocker htaccess to your public_html to help prevent hack attempts and spambots, optimize your database(s), and/or optimize your scripts. Your webmaster or the script developers should be able to assist with this.
Bad bot blocker download
Spambots are a very common reason for a 508 error. Make sure your comments sections or forum areas are not receiving massive amounts of SPAM. If so, find ways to stop this from occurring.
Enable caching. When it comes to PHP scripts caching is very necessary to reduce load. This prevents the processor from being hit on every single request as opposed to processing once and sharing that processed information multiple times. Most PHP scripts now days have a caching module available.
This can also occur when your account is being attacked by spam bots as a result of a poor captcha or an out-dated script. You would need to update and secure your scripts in such a case as well. Using our bad bot blocker may be beneficial in such a case.
You can also check the document root of your websites for any error_log files, if you find an error_log file, you should take a look at the recent entries and fix any errors that are reported. Optimizing your database tables (if any of your sites are MySQL driven) via PHPMyAdmin is also a good way to keep things running smoothly.
