Okay, so here are the salient lines from the error logs (I have two vhosts, webmail and wiki, running through suexec – if I put them through the regular FCGI process without suexec, I don't have this problem). Also, I should not that this problem does not occur on my testing VM, only on our production server (so I'm not quite sure what the problem is).
