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 :-)
