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.

These are usually harmless, unless they go up in a
sudden spike or are 
accompanied by other problems, its ok.

This is also mostly harmless, it indicates that cyrus
was unable to 
unlimit its max # of file descriptors, which is
generally ok.

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 ?
