 * I thought this may have been related to the other post regarding .htaccess code
   flushing, but it looks like a separate thing.
 * Plugin: BPS Pro
    Issue: When checking/selecting the Developer Options >>> PHP
   Errors — Enables sensor for alerts generated from PHP option and visiting any
   of the BPS Pro plugin pages some kind of large dump or object flush happens. 
   BPS Pro has a plain text php error log that logs php errors. When visiting any
   of the BPS Pro plugin pages with the php error option selected 20MB of data is
   dumped into the BPS Pro php error log plain text file and BPS Pro plugin pages
   will no longer load since it appears that 20MB is also trying to be loaded in
   each BPS Pro plugin page visit.
 * My hunch is some sort of object flush gone whacky. Still looking through your
   code.

 * The dump seems to contain every single WordPress function, Server variables, 
   system variables, all plugin and theme data and variables. You get the picture–
   massive dump of info, which ends up being around 20MB of data. 😉 Still looking
   for the source of the issue.

 * Ok isolated it to this file/code below.
 * commenting out debug_print_backtrace() keeps the problem from happening. If I
   have some spare time I will dig deeper.

       public function EventError($errno, $errstr, $errfile = 'unknown', $errline = 0, $errcontext = array()){
       		if($this->_avoid_error_recursion)return;
   
       		ob_start();
       		//debug_print_backtrace();

 * Hi,
 * Thank you for reporting this. We are looking into the issue today. Should we 
   need any further information we will get back to you. If not we should release
   a fix later on this week.

 * Just starting to dig deeper on this, but wanted to give you some more general
   info on the what, when and where of the issue.
 * It is not isolated to just my plugin or the php error log in BPS Pro. Using the
   Apache Server’s default php error log and accessing another plugin’s settings
   page that has a minor php error occurring causes the identical massive dump of
   data issue.
 * So the condition is – if a php error is detected/occurs in any plugin then the
   debug_print_backtrace() function is dumping everything it can find. Probably 
   some kind of loop restriction would need to be added or something similar to 
   the concept of “only return X instead of X, Y and Z”.

 * Also what is then causing a plugins page to not load is the server runs out of
   memory during the dump.

 * This option seems to do the trick, but unfortunately it was introduced in 5.3.6
   so you would need some sort of fallback / alternative for older versions of PHP.
 * `debug_print_backtrace(DEBUG_BACKTRACE_IGNORE_ARGS);`

 * or maybe get off easy by doing a PHP version check. 😉 if php version < 5.3.6
   don’t do anything. if php version >= 5.3.6 do something.

 * Hi,
 * Thank you for posting the ticket.
 * We are including a new option in the next plugin update to make capturing of 
   strack trace optional, thus avoiding such situations. Having said that, as a 
   developer you should / would be typically aware that when enabling such developer
   options, all data will be logged, including the 20MB of data your plugin generated.
 * While I trust the above addresses your issue, do not hesitate to get in touch
   should you have any further queries.

 * It is already an optional thing so not sure what you mean by that. Anyway my 
   Dedicated Server is not capable of handling 20MB of data dumped all at one time
   so no way a Shared server would be able to handle that dump size. At least not
   in that format. 😉 Possibly outputted as HTML might work, but not a 20MB string
   ha ha ha.

 * Either way I was just pointing something out. Not really a problem or a ticket
   and just a heads up. It is documented in our KB now so if someone has these symptoms
   we know what to ask and how to “fix” it. 😉

 * Just a friendly heads up and not an issue or problem – resolved.
    FYI – yep the
   20MB dump in HTML format worked great – server had no problems handling that.

   Notepad++ while trying to view a 20MB string. 😉

   the handling of such files, so stay tuned with us 🙂
