 I'm using nginx as a proxy for my wp.

 By default setting for 'fastcgi_buffer_size' is set to 4k.

 If you do a headers_list() during wp_logout. you will see the size is
 almost 3k.

 So if we combine this wp_logout with other hook which also sets couple
 headers. Sometimes this 4k limit reached and blowing out the buffer and
 resulting in a HTTP 500 error. The fix is to increase the
 'fastcgi_buffer_size' setting. But increasing this setting will cause
 unnessasary memory usage for regular use.

 So Its recommended to decrease this huge list of setcookie especially each
 of this is so long.
