Description:
------------
System requirements: php5.6 / centos5 / APCu Version (4.0.11)

environment:
I set up multiple sites with virtual host and use APCu.

problem:
Apc.mmap_file_mask is different for each site, but somehow the value is shared.

For example:
Virtual Site A:
apc.mmap_file_mask: /tmp/apc.AAAAA

Virtual Site B:
apc.mmap_file_mask: /tmp/apc.BBBBB

Virtual Site C:
apc.mmap_file_mask: /tmp/apc.CCCCC

In the case of, the cache value generated at virtual site A can be confirmed from the APCU management site of virtual site B.

Question:
Why is the cache shared despite different apc.mmap_file_mask values ​​for each site?

You are using ancient versions of PHP and APCu; please try with
current versions.
