well the problem is not with cpanel or whm. the problem is how the server is behaving.
see for this instance.
this is what i get while importing a vb database from xenforo.
not a mysql error. not a php timeout error. just a 404. when i a running a script from the admin panel on xenforo. the script works for a while. and then ends up on this screen.
this problem is not limited to xenforo. it is happening with wordpress as well. i try to publish a post, i get a 404 screen! it happens randomly.
it is pretty clear that either php or mysql is timing out. the limits are pretty generous.
there are no errors recorded in apache logs. there are no errors recorded in mysql logger. this has been baffling my server guy. he is asking if xenforo produces its own log. i cannot find any. and from my experience using wordpress, it too do not have an internal logging mechanism.
i am getting this one user import. tons of users. probably i should remove users with zero posts from my vB. but then i am just testing around the import feature right now. would not migrate till stable version arrives.
