I have :-)
The term might be referring to Zend Accelerator, which precompiles and 
caches PHP code. Or to Turck MMCache, which does the same thing, in 
roughly the same fashion.

Such an accelerator usually keeps some system status around that 
wouldn't persist in an unaccelerated environment. If PmWiki happens to 
rely on just this status being reset on every invocation, it might very 
well do, uh, unexpected things.

To Doug: I believe it would help Patrick if you could find any error 
messages that PHP is issuing before the crash. Check the Apache error 
log (your ISP should have told you where to find it).
Alternatively, you might get a WWW page with a nice error message if you 
changed display_startup_errors to on; depending on your ISP's 
configuration, you'd have to do that either in php.ini 
(display_startup_errors = On), or in httpd.conf or .htaccess (php_value 
display_startup_errors On). There are some other error reporting 
settings you can tweak, all documented in php.ini or on php.net.


Of course, it may all be related to the accelerator botching something 
badly up. Accelerators tend to do that sort of thing, and the ISP might 
be in heavy gyrations to get that upgrade done :-)
