Hi Paul,

first of all, sorry for replying almost a month later.

Cached connections go down, but seems to be something wrong with the 
counter. Pimpstat reports negative values for cached connections during 
nights, when there is no activity on the webmail.

This behaviour has been the same since we started using imapproxy. We 
use Ganglia to graph pimpstat output, and every night we can see 
negative values for cached connections.

For instance, "pimpstat -c" showed this morning at 6:45 these values:

--8<--
  4 Current Client Connections
  263 Peak Client Connections
  296 In Use Connections
  388 Peak In Use Connections
  -248 Retained Server Connections
  -1 Peak Retained Server Connections
  38075843 Total Client Connections
  38013935 Total Client Logins
  36138758 Total Reused Connections
  1875185 Total Created Connections
  0 Cache Hits
  0 Cache Misses
-->8--

Should we care about the negative cached connections count?

Regards.
