Re: message in /var/log/messages
I m running a Red Hat Psyche 8.0
(fully updated)
i've found this :
http://asg.web.cmu.edu/cyrus/download/imapd/faq.html
Q: I'm getting messages in imapd.log like:
Sep 11 17:23:55 ogg lmtpd[773]: DBERROR db3: 16
lockers
Sep 11 17:23:55 ogg lmtpd[1409]: DBERROR db3: 17
lockers
Sep 11 17:23:56 ogg lmtpd[1508]: DBERROR db3: 9
lockers
Sep 11 17:23:56 ogg lmtpd[776]: DBERROR db3: 9 lockers
What's wrong?
A: Nothing is wrong. These messages are logged
whenever Berkeley db encounters lock contention, but
isn't necessarily a problem by themselves. This is
especially likely when you have an empty or small
duplicate delivery database and are receiving a large
volume of e-mail.
Berkeley db 4.0 has a bug where the number of lockers
isn't decremented properly, causing this number to be
unreliable.

The only 2 things left, which are bothering me now ,
2 king of messages
in syslog:
1:
lmtpd[10260]: DBERROR db4: 9 lockers
These are usually harmless, unless they go up in a
sudden spike or are
accompanied by other problems, its ok.
2:
master: setrlimit: Unable to set file descriptors
limit to
-1: Operation not permitted
This is also mostly harmless, it indicates that cyrus
was unable to
unlimit its max # of file descriptors, which is
generally ok.
But, may be there's something I can do to fix those
bugs , to live with
clean logs...?
change the code? turn off logging? Since the setrlimit
one only occurs
at startup, it shouldn't be that big a deal. I can see
the DBERROR one
being more annoying I guess, but it would require a
change to the code.

So i don't think this is really a problem .. ?? isn't
it ?

Re: message in /var/log/messages
It all depends on how many simultaneous connections you're trying to serve. If you only need to serve a couple hundred, you're going to be fine with this. However, if you're going to get up past 3-400 simultaneous connections, the master is going to start to need to have more file descriptors open in order to maintain communication with the worker threads. I'm having trouble remembering off the top of my head what order the open file descriptor number is going to be in relation to the connections, but if you have more than 1024 simultaneous connections, you will certainly run into this. If you're on a small site, then you'll be fine, and can just ignore these. If you're on a large site, particularly with most users keeping imap connections open all the time, you might bump up against the max file descriptors problem. It's your call.
