500 Internal Server Error - Every single page

I've been doing nothing but google for the last 4 hours unfortunately. :\

I rebuild apache, re-uploaded all of the vB install files, and even went as far as to refresh my database from this morning's backup. Now my pages just drop the connection, and my log is full of this:

[Sun Mar 22 23:49:39 2015] [notice] child pid 19537 exit signal File size limit exceeded (25)
[Sun Mar 22 23:49:39 2015] [notice] child pid 19542 exit signal File size limit exceeded (25)
[Sun Mar 22 23:49:39 2015] [notice] child pid 19544 exit signal File size limit exceeded (25)

Google tells me that it means that my log files are over 2GB, but I've done a find on all files and there are no files on my server at all that are even near 1GB, let alone 2GB.

I fear I'm just making this worse, so any other input please let me have it. I'm DOA and up all night until I fix this, ugh.

I'm back up. No clue what actually fixed it. Combination of:

- Rebuild apache / flush all logs
- Disable suphp
- Re-upload everything
- Revert to an earlier DB
- Recompile apache some more
- Rotate logs again
- Magic...
