at 13:47 how did you suddenly get from that php code to the read/write result? How would you know which result too look for once you found the php line?
@brusdaar This is a big 4k string of text, and the beginning of the line didn't show up on the screen at 13:47. A little later at 14:00 I move up a bit and you can see the beginning of that line (one line down from the cursor) which begins with "read(11,\1...." . At 14:00 can you see the read, but not the smoking gun (the embedded PHP sleep) although it is there. The PHP code came from a mysql write/read (query/response) action, but it wasn't clear because you couldn't see the whole line.
@iamfaze I didn't mess with the apache timeouts, I think they were default for CentOS. You're right though, it seems the timeouts are often much tighter than that.

Did you bump up the Apache timeouts? IIRC you dont typically get that long to look for it.

I wonder if its possible to use STRACE to see if a process is trying to delete files/folders...
