I prefer to merge the two bug reports, because the problem is exactly the same. > This occurs on a XEN based virtual private server at a commercial hosting > facility. > Jan 7 04:54:49 xxx dovecot: Time just moved backwards by 81 seconds. > This might cause a lot of problems, so I'll just kill myself now. > http://wiki.dovecot.org/TimeMovedBackwards Are you running ntp on your server? You should, it would prevent your clock to be moved backwards by 81 seconds all together, and would probably fix this behaviour. > A timebomb like this renders dovecot unsuitable for use on servers as all > email clients will be unable to connect to the mail server until an > administrator discovers the problem and restarts the mail server. To be honest, I run my mail servers under Xen, I run dovecot and I never had such an issue. Again, I think that having the clock going backwards by 81 seconds is a problem and should be fixed, instead of considering dovecot a time bomb. I'm pretty sure that upstream won't fix this (as stated in the wiki page), and I'm reluctant to add a wrapper script to simply restart dovecot in these situations: you would never discover the real problem. All in all, such a wrapper script is pretty easy to write if your server is affected by clock moving too fast; we can probably provide one in the package, as an example. > - warn administrators that they are installing a fragile solution during > install. I don't think that dovecot should be considered a fragile solution.
