Errors and dovecot crashing...

2017-12-06 Thread SH Development 
Our production dovecot/postfix server has been stable for a number of years.  
In the last month or so, we are seeing increasing errors such as these:

Dec  6 15:51:20 mail dovecot: imap(redac...@lilythicket.com): Warning: 
Transaction log file 
/home/vmail/lilythicket.com/diana/Maildir/dovecot.index.log was locked for 322 
seconds
Dec  6 15:50:54 mail dovecot: imap(redac...@theormans.com): Warning: Maildir 
/home/vmail/theormans.com/connieorman/Maildir/.Junk: Synchronization took 66 
seconds (1 new msgs, 0 flag change attempts, 0 expunge attempts)
Dec  6 15:51:43 mail dovecot: master: Error: service(pop3-login): Initial 
status notification not received in 30 seconds, killing the process
Dec  6 15:51:43 mail dovecot: master: Error: service(pop3-login): command 
startup failed, throttling
Dec  6 15:51:43 mail dovecot: master: Error: service(imap-login): child 5868 
killed with signal 9
Dec  6 15:51:43 mail dovecot: master: Error: service(imap-login): command 
startup failed, throttling
Dec  6 15:55:31 mail dovecot: imap-login: Fatal: Corrupted SSL 
ssl-parameters.dat in state_dir: Truncated file
Dec  6 15:55:32 mail dovecot: pop3-login: Fatal: Error reading configuration: 
Timeout reading config from /var/run/dovecot/config

And so forth.  Seems to be all over the place.  The server slows down to a 
crawl.  Restarting dovecot or postfix has no effect on the problem.  Only a 
server reboot solves it, temporarily.  Sometimes for weeks, sometimes for 
hours.  The hard drive SMART status reads okay.

During this time, of course, users cannot connect to check their email.

Thoughts on where to go to troubleshoot this and why it’s happening?

Hi,


ldap_bind: Strong(er) authentication required (8)
 additional info: BindSimple: Transport encryption required.




If you are using recent (4.7) samba, your problem could be that it 
requires ssl ldap by default, unless you configure


ldap server require strong auth = no

in smb.conf.

Many thanks!

That works perfectly.
