Ok, more information. I closed all my clients and checked the connection
count. It was still at 57, so I cleared the user with "doveadm kick",
count was then 0. I launched Thunderbird again and the count went to 16,
then started my tablet and it when to 3.
I am thinking I still have a issue as why when I closed all the clients
I still had 57 threads/connections open, and after Thunderbird settled
down it dropped its connections to 3, but over time that connection
count rises.
In the 5 min while writing this the connections jumped to 30.
I turned off Wifi on my tablet so the client would use a different IP,
the connection list went to 41
Now it went back to 59 open connections. I turned my tablet back off,
its staying at 59. I kicked the user again. I am going to keep my tablet
off, maybe it's the one causing this.
Is there a way to find more information about what is going on in one of
the pids? It would seem like one of the clients is opening up a
connection and for some reason its not dropping and it keeps just
opening up new ones, but there are no errors in the log files. Once I
turn off the client the connections are not clearing.

Thanks for the command, that is very useful.
That user is actually me, I know why where are so many open. I have my
computer, and two tablets, and since I am using server side filtering
(procmail) I have to set watch on all the folders that are filtered to
or I miss a email. But I am doing the same for about 4 other users
accounts I also monitor, so I am not sure why it's just my username
that is doing that. I am going to shut down all the clients one at a
time and see what client is opening all those connections.
Once I close the client, I assume the connection should also close and
the count go down, correct?
I turned off both tablets and the connection count for my username
still is at 60, since I am writing this email with my computer client
I will send it and close my client and see what happens. Thanks! - Jeremy

That was the first thing I tried, I lowered the cache connections
in Thunderbird. Actually the max connections was 50, not 500, but
I could see why as I do have a lot of folders, but what is odd is
I have other mailboxes that have even more folders, but it's only
one mailbox that is trowing the error.
"# ps -axww | grep imap" does not give me the same results -
.....
19897 ? S 0:00 dovecot/imap
19900 ? S 0:02 dovecot/imap
19901 ? S 0:00 dovecot/imap
19902 ? S 0:00 dovecot/imap
.....
I wish it did give me the mailbox, is there a option to get it to
give me that information?
Try "auxw" on your "ps". I.e., add in the "u" which will get you
the user detail in the first column, otherwise you just get the
process id.
Thank you! That worked, I piped the output to a file, grep the
username and sure enough there are 60 lines. So I guess going over
50 was a possibility.
Learn something new every day. I set the maximum to 100 so I should
not have any errors on that anymore.
Rather than simply upping the limit I think a reasonable question to
ask is why/how they are managing to do that. That's a lot of open
folders.
By the way, the single command:
ps auxw | grep imap | cut -d" " -f1 | sort | uniq -c
will get you a nice list with the users and their connection counts.
