Comment (by walkinverse):

 Replying to [comment:1 joyously]:

 continued after removing the plugin. If it was a core problem, we would
 all have big log files. But we don't.

 No, this is not a plugin issue.  As a further test, I deleted all non-core
 cron jobs as well as deleted every single plugin to the bare minimum. Yet,
 it still generates thousands of lines of warning.

 In addition after further research, many were having this exact same issue
 and it was supposed to be resolved in the update.  Maybe something was
 missed as I am getting the same issue.

 {{{

 In the actual file error happen here:

 line 272:

 {{{#!php
 $num_args                           = count( $args );
 }}}


 line 286:

 {{{#!php
 } elseif ( $the_['accepted_args'] >= $num_args ) {
                 $value = call_user_func_array( $the_['function'], $args );
 }}}

 The countable seems to point to a database issue.  The same issue in the
 previous release.  I also updated to 5.1.1 and still receive this issue.

 {{{#!php
 public function apply_filters( $value, $args ) {
 }}}

 Also, all custom functions have also been removed.
