This is systemd doing its "magic" (kill all control group processes), see https://dovecot.org/pipermail/dovecot/2016-June/104546.html for a

Daniel, thanks so much for the detailed pointers. So it turns out to be both the evil that is systemd and an overzealous upgrade script. Apollon, should I raise a Debian bug for this? As for reasons, how do 50k proxy session on the proxy servers and 25k imap processes on the mailbox servers sound? Even on a server with just 6k users and 7k imap processes that causes a massive load spike and a

Yes, that would help too.

Hello everyone, I work in a setting where remote logins are usually authenticated with SSH user keypairs, but many target accounts need to have a password set nonetheless (to use with sudo, log in via remote KVM, etc.) and cannot be put under a central user administration like LDAP. Enter a corporate password policy that requires passwords to be complex, different everywhere, and of limited

Hello, I have asked on the postfix mailing list for a solution, how to encrypt incoming emails with public gpg key My original idea was to use a smtpd-milter, which would encrypt all incoming plaintext messages of given user, using the users public gpg key. This way, it would look as if the original sender has sent the message encrypted. Somebody suggested this might be better done in Dovecot,

That log didn't do much help, can you try enabling mail_debug=yes for a moment and see if it gives any more insight?

I have seen some strange error log messages in our dovecot server (2.0.15, RHEL 5.7x64, mdbox+zlib, local storage, high load) Dec 14 22:01:27 buzon dovecot: imap(fmcarrasco): Error: /indices_dovecot/indices/07/47/fmcarrasco/mailboxes/INBOX/dovecot.index reset, view is now inconsistent Dec 14 22:00:27 buzon dovecot: imap(cfp): Error:

Hello, given a small organization. There are *personal* mailboxes (mailbox per user, incl. subfolders et cetera). The users can share specic folders via the ACL (we call it "other users/", Dovecot calls it "shared" folder. Additionally there are mailboxes Dovecot calls "public" (we use the term "groups/"). They are not associated with a specific account,

Hi all, I've uploaded STAR (Spike Train Analysis with R) on CRAN two days ago. The package is designed to analyze neuronal spike (action potential) trains. It uses S3 classes and methods and makes heavy use of other CRAN packages like gss, R2HTML, mgcv, survival. * Analysis of both spontaneous and stimulus evoked activity is implemented for single neuron spike trains as well as for many

I finally got (mostly) what I wanted. In an attempt to figure out how to get nls to deal with a non-differentiable function, I had (stupidly) 'simplified' the problem until it became singular. Can I do something to make optim() less sensitive to my initial guess? For this example, I get a lousy solution if I make the initial guess for t0 = min(t) = 0.05. Thanks again, -- Robert Merithew

I have sucesfully normalized the data using vsn, however i would like to normalize using spike in controls. My controls are annotated as CTL-1 to x and i would like to do etiher a normalization by block per array or the mean of all the controls per array. The gal

If I read this correctly, starttls will fail due to the MITM attack. That is the client knows security has been compromised. Using SSL/TLS, the MITM can use SSL stripping. Since most Postifx conf use "may" for security, the message would go though unencrypted. Correct??? Is there something to enable for perfect forward security with starttls? ? Original Message ?

I am running Asterisk V 1.4.22 Twice during the last two days the Context Switches on our box has gone from about 7K to 80K in 2.5 hours. The load average would spike to 17, drop to 0.35 then spike again. When connecting to the console 'core show channels' will list the channels but not total calls. 'restart now' had no effect, the only way to stop Asterisk is to kill the
