Thanks! Just so I get the error message into a searchable form, let me 
enter this for posterity's sake:


Ouch! ap_mm_create(1048576, "/var/run/httpd.mm.6883") failed
Error: MM: mm:core: failed to acquire semaphore (No space left on 
device): OS: Invalid argument

It can be fixed with Martin's posted scripts. (Note I just squished them 
into one script.)
