So annoying that the stable release of debian isn't supported anymore. 
It seems like if you wait so long to release the stable version that it 
isn't supported anymore, it sort of defeats the purpose.

Anyway, here is an example of some processes that are getting big:


24328 cyrus     20   0  147m 6236 5004 R 27.4  0.2  22:07.21 imapd 

27549 cyrus     20   0  147m 6512 5116 R 27.4  0.2 155:41.26 imapd 

30097 cyrus     20   0  147m 6280 5052 R 27.1  0.2  93:44.08 imapd 

Unfortunately I can't tell you anymore about these processes, since they 
are just cut and pasted from a terminal where I checked top before 
restarting cyrus, and cyrus has not regrown yet.
