So thats saying the problem is in a PHP app (or the PHP module), so add the debug files for PHP so can zero in on what specifically is happening with either the app, PHP or a PHP module (zend, ioncube, etc.).

I got rid of the ioncube app, still glitching up. How would you find out from PHP what's wrong if its not kicking errors to the php log? A fail looks like a white screen, no errors to apache logs, either for the subdomain or the process, no php logs. How else would I find what's breaking in PHP?

try running your app through php from the command line. I catch all kinds of problems with that

Trying to figure out how to access a WP page through command line php.

php /var/www/vhosts/domain.tld/httpdocs/path/to/file.php
But be careful! You may need to manually tell php which php.ini to use. There's a command line switch for that. I think if you don't specify one it doesn't use one and uses defaults. This may have changed in later version, of course. Not done this in ages.
I'm not completely sure how well this might work, and remember that the page will be output as html code on your screen (unless it crashes)

Excellent faris, got that down. Now how to pass arguments? Or in the case of WordPress, how to access a specific page with the command line.
Re: New Kernel Less Stable than Last Kernel

You'll need to use a tool like curl/wget/lynx to access the page via HTTP, as WordPress pages don't exist as a file on the filesystem.

I'm pretty sure that just accesses the site like any other client.

I'm sorry, I missed what you were trying to do here and that you actually didn't want to go through Apache. But I don't believe there is another way in this case.
What is error_reporting set to for this script? I've seen lots of cases where scripts (or people) set error_reporting to some value that prevented logging the error message.

Hi Breun,
I set all possible errors (even deprecated and notice) to go to the php error log. In an attempt to fix this, also set them to all display except deprecated and notice. Anyway, I found the culprit. Realized eventually that it was just WordPress sites in *this* case, and started disabling plugins until the problem went away. It was WP_Super_Cache. Haven't tried to make it work yet, but disabling has stopped that particular error.
I'm still experiencing crashes, had another one last night. I'm watching this thread because it seems to have a lot of the same features.
https://www.atomicorp.com/forums/viewto ... 446#p31446
Differences are I'm running on a dedicated box and not a virtual. I've gone to hourly apache restarts to gain some stability. Stretched out the crash interval from approx 1-2 per week to 1 per month. This is not good.

Keep in mind that bus errors are generic, so that another persons bus error is unlikely to have the same root cause as yours and therefore the solution to their problem is not likely to resolve yours.
To find the cause of a bus error you need to analyze your core dump files:

Thanks mikeshinn.
OK - core dump with PHP backtrace via .gdbinit.
Ultimate error is PHP saying: "Cannot access memory at address."
I've disabled the offending WP add-on, let's see if it happens again. I'm suspicious that memory access errors aren't script specific.
