Our PHP process appears to be crashing when uploading images. The PHP script resizes the image using Imagick and then updates MySQL. After uploading ~30 pictures (which are done one at a time and each using their own HTTP request), we get an ERR_EMPTY_RESPONSE in Chrome. I go into cpanel and checkout the PHP process and the PHP process doesn't exist or a new ID is there. After some more trials, I noticed our I/O Usage is getting close to maxed (1,048,576) when uploading images and then drops back down.
Is the maxed I/O killing the PHP process? There are no error logs that I can find anywhere that tell me what is going on. Everything I've read both in the forums and elsewhere simply suggests I/O gets queued and thus things become slow but in my case it appears to be killing the process. Any thoughts?
