I suspect I've either done something horribly wrong or found a weird
bug, probably the former. I'm running PHP 5.2.13 on Solaris 10 under
Apache 2.2.14. Memory usage is 98.8% free (default 1 slice of 30MB).
Here are stats on the cache:

Cached Files                    1 (288.2 KBytes)
Hits                            4146
Misses                          3579033
Request Rate (hits, misses)     358.68 cache requests/second
Hit Rate                        0.42 cache requests/second
Miss Rate                       358.26 cache requests/second
Insert Rate                     0.00 cache requests/second
Cache full count                0

And here is my config in php.ini:

error_reporting = E_ALL ^ E_DEPRECATED
apc.report_autofilter = 1
log_errors = 1

If I restart apache, a different file gets cached each time (it rotates
between a very small subset of all of the PHP files in horde).
Sometimes, 2 or even 3 files get cached, but I've never had it go above
3. I've been googling around and reading the list archives but I can't
find anything that seems to be related to this. Am I misunderstanding
the purpose of APC? I thought that it would attempt to cache all PHP
files that are requested.

I turned on the report_autofilter in an attempt to diagnose the issue,
but nothing shows up in the error log. Here is the config as shown by

apc.cache_by_default            1
apc.canonicalize                1
apc.coredump_unmap              0
apc.enable_cli                  0
apc.enabled                     1
apc.file_md5                    0
apc.file_update_protection      2

apc.user_ttl                    0

Any help would be greatly appreciated.
