hi list, we recently saw the following weird behaviour on samba v3.0.13 with MacOSX panther and tiger as clients --setup-- [share1] path = /data valid users = @admins force user = administrator inherit permissions = yes force create mode = 770 force directory mode = 2770 [share2] path = /data/folder valid users = @noadmins force user = administrator inherit permissions = yes force create mode

Hello, We've got a pretty substantial dovecot installation (versions 2.1.7 and 2.2.13 on the backends, but tested with 2.2.24 as well) and this is the relevant config snippet from 10-master.conf: --- default_process_limit = 1024 default_client_limit = 16384 [...] service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge

Here's what I'm trying to do. I have a spam filtering operation as a front end for other servers. I've created a virtual server for spam storage where the user will be able to log in using squirrelmail/dovecot to review and release their spam. The email is stored in maildir format. Piecing it together I can use squirrelmail to pipe the email into something so that if a use finds a

> 1500 IMAP sessions will eat up about 3GB alone. Are you saying that Dovecot needs 2MB of physical memory per IMAP session? If I want to support a max 100,000 IMAP sessions per server, I should configure the server to have at least 200GBs of SWAP? > On Feb 10, 2017, at 3:58 AM, Christian Balzer <chibi at gol.com> wrote: > > On Fri, 10 Feb 2017 01:13:20 +0530 Rajesh M wrote:

Seems that these IMAP processes are long lived processes (idling most of the time) that don?t need that much of the contents of real memory available for much of the life of the process. I use a database proxy in

Thanks for the info. I do have one further question for you. On your servers that are currently handling 50k IMAP sessions, how many users does that correspond to? Since many users will have multiple IMAP sessions on multiple devices, I?d like to hear about some real-world numbers that could be used for budgeting a new project like mine. Also, do you use Dovecot IMAP proxies in front of your

thanks for your help happy to say that the performance dramatically improved after i use the high performance settings from here http://wiki.dovecot.org/LoginProcess grep Login: /var/log/mail.log.1 |wc -l with the mail.log being of a typical, busy day. 412992 i also picked up the imap and pop3 connections during peak hours [root at ns1 domains]# doveadm who | awk

christian the servers i currently own are dell servers. The servers i plan to buy are Dell R530, 2U rack servers with 8 x 3.5 inch drives, with 64 gb ram each, Hardware raid. I am thinking of 2 X 300 gb ssds raid1 and 6 x 2 tb drives in raid10 for data. I do not have any experience in setting up drdb (that would be my next step) ... primarily using standalone servers with hardware level

Hi guys, first of all let me say "hello" to everyone. Its the firt message for me in this list and I'm pretty happy that I'll be able to finally start working with LLVM. I've a question for you all if you can help me: a few years ago I've implemented a simple VM for a language we're using in my company. The VM JIT compiles a simple bytecode and executes it.

Do these statements yield identical types of objects? x = 3 and y = c(3) That is, intrinsically, is x, like y, a vector of length one, but created with abbreviated syntax? More simply: Are scalars really trivial vectors? Thanks. -chris

Hello, this is on Debian Jessie box, dovecot 2.2.27 from backports, imap-hibernate obviously enabled. I've been seeing a few of these since starting this cluster (see previous mail), they all follow the same pattern, a user who accesses their mailbox with both POP3 and IMAP deletes mails with POP3 and the IMAP (imap-hibernate really) is getting confused and upset about this: --- Apr 6

This is definitely a newbie question but from the documentation I have not been able to figure out what the partial sort option on the sort method does. I have read and re-read the documentation and looked at the examples but for some reason it doesn't register. Would someone attempt to explain what sort with a non-null partial array of indices does? Thank you. Kevin
