I have web services deployed on an Apache / Mono server in my production. It works fine, but sometimes it throws 500 errors (internal server error) in my Apache log randomly (that is, it throws this error regardless of the web service) and subsequent service calls after that cause error 503 (service unavailability), which leads to the collapse of Apache / Mono. I need to restart my Apache / mono to start the service.
So my questions are:
- What is the cause of error 500 (internal server error)?
- What is the cause of error 503 (server temperature not available)?
- Are these errors caused by memory overflow on the server?
- Is this a problem due to an Apache configuration problem or code issue?
