OK. I have tried everything I know. I have converted the user.sub file
from flat file to skiplist and it still gives me the same issue. I have
also created a new test install of Debian stable with just the same
setup but using 2.2.13-10 and everything is the same. When I am using
cyradm in the command line even loged in to the user accout and
subscribe to a folder I just created, I again get:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+
COMMAND
3489 cyrus 25 0 81212 3968 3116 R 99.9 1.3 4:39.88
imapd
I have converted everything over to skiplist even quota to make sure and
as far as I am sure it is not related to that. My
/usr/lib/cyrus/cyrus-db-types.active reads:
ANNOTATION skiplist
DBENGINE BerkeleyDB4.2
DUPLICATE skiplist

PTS berkeley

I am totally at a lose and have exhausted everything I know and have
read, researched. I even bought the book of IMAP which is a very good
read by the way.
Thanks in advanced.
