First of all, I need to establish which limit is causing ‘508 Resource Limit is Reached’ error; The majority of 508 errors are generated by cPanel based servers that are running Cloudlinux. The 508 error is generated by one of two things occurring on the server.
Memory usage;
Entry processes exceeded;
Contrary to belief, CPU limitations do not cause 508 errors directly. If the CPU allocation of an account is reached, it will stay at this maximum and slow down other processes running on the server. This can cause the amount of entry processes to go up as requests cannot be fulfilled as quick as they would be without a limit in place, potentially causing the entry processes exceeded trigger of a 508 error.
Through cPanel access of shared web hosting account and the server is running Cloudlinux, I can check the resource usage and find out the route;
If hosting provider has limits lower than the requirement of the website
If website traffic spikes
If there are rogue processes, back-end jobs or cron jobs that are impacting on the resource usage
If Web Crawlers, Search Engines or Denial of Service Attacks; The issue may occur; However, I need to find out the exact source which is causing this;
Please ping me on your convenient time; Lot's of points are there to discuss with you; Hoping to have a prompt and affirmative response by your end;
