Skiplist causing DB problems? (UPDATE)

[Jason Williams]

Good morning everyone.

Thought i'd post something very interesting I noticed this morning when I 
came into the office.

I started this thread last Friday, as I was testing two idential servers 
(hardware wise) with different configs.

Anyway, I came in this morning and was looking around in the server that 
was compiled with skiplist.

What is weird is that I am no longer receiving those errors my my message 
log...

 >Jan 16 16:46:02 obsidian ctl_cyrusdb[169]: checkpointing cyrus databases
 >Jan 16 16:46:02 obsidian ctl_cyrusdb[169]: DBERROR: error listing log 
files: DB_NOTFOUND: No matching key/data pair found
 >Jan 16 16:46:02 obsidian ctl_cyrusdb[169]: DBERROR: archive /var/imap/db: 
cyrusdb error

Those are no longer showing up...the checkpointing does it's job and 
reports no errors.

This is very intriguing to me. Did cyrus just need some time to figure out 
things on it's own? Granted, the last time I touched this server was Friday 
afternoon.

Anyone have any idea on WHY all the sudden the errors are gone?

I appreciate the help.

A befuddled Jason...
