I’ve just migrated from “old style” VPS to the new VPS with SSD. The bad performance of the new VPS is another matter but I have some issues with Apache with its default configuration.
I’ve been running a small sized Xenforo forum on the VPS for past 5 years or so without much problems. Some admin operations failed but that could always be cured with temporary RAM bump.
Not anymore. My VPS has twice RAM than before with max utilization below 50% of that. The CPU load is also small. But any attempt to upload a new style ends with server errors. It’s either 500 Internal Server Error (with FastCGI) - with “Premature end of header” in the log, or Gateway Timeout (with normal CGI).
Those problems are probably related to some timeout values set in the Apache config which isn’t accessible for me.
Is there any way to fix this?
