XF 1.2 Question ( not a problem ) about server error log

[K a M a L]

I was having problems with my server ( out of memory errors ) , I moved to a new dedicated server with 32 GB Ram and everything is going well
but after I moved to the new server I got a new type of errors such
"
'Usernames must be unique. The specified username is already in use.'
'Email addresses must be unique. The specified email address is already in use.'
'Please enter a name that is at least 3 characters long.'
'Please enter a valid message.'
"
these errors are normal errors , but should these errors be in "server" error log ?
why this type of errors was not showing on old server error log and now showing up on this server
is there a setting I can change to stop logging such type of errors ?

These errors shouldn't be logged here. If they are, it likely indicates that there's a conflict or misconfiguration within PHP. We have seen opcode caches and optimization/debugging extensions (in PHP) cause things like this. I would recommend disabling these extension to see if the errors are removed.

Unfortunately, little can be done about this in XenForo. As the code is written, this should never happen; when a conflict arises with PHP extensions, it actually runs code diferently than as it's written.
