multiple statuscache db (only Invoca rpm?)

[Marco]

Hello cyrus user,

  on my cyrus-imapd server I see this:

man imapd.conf:

        statuscache: 0
             Enable/disable the imap status cache.

        statuscache_db: skiplist
             The cyrusdb backend to use for the imap status cache.

             Allowed values: berkeley, berkeley-nosync, berkeley-hash,  
berkeley-hash-nosync, skiplist

        statuscache_db_path: {configdirectory}/volatile/statuscache.db
             The absolute path to the statuscache db file.


In my imapd.conf I set:
statuscache: 1

Every time I restart cyrus-imapd, a copy of  
/var/lib/imap/volatile/statuscache.db appears on /var/lib/imap path:

#ls -l /var/lib/imap/
total 68

I have to remove it by hand...

I don't know if this happens only on Invoca rpm which I use:
