I get the following error: Fatal: epoll_create(): Too many open files (you may need to increase /proc/sys/fs/epoll/max_user_instances) Works fine if I start it by hand, I'm guessing it has to due with the environment heart starts it in? My first thought was to do exactly what the message suggests, but my kernel doesn't appear to define max_user_instances, but there is a

Hello, this patch adds ioloop handler using Linux 2.6 epoll API. I'm not sure is it ready for inclusion right now, but it works for me and survives deadconn test with 1024 simultaneous connections. Please take a look and comment. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke at donpac.ru | PGP key: wwwkeys.pgp.net -------------- next part -------------- A

Today I finally caught up with my mail. I've now read all the mails from the Dovecot list from this year and all my private mails from last few years (totaling around 500 unread mails). If you think there's still something I should have replied to, please re-send it because I've either missed it or just skipped it for some reason. (Except there are still a couple of mails from this

I am running dovecot 1.0 beta3 as a front-end proxy, and getting the following error when using epoll. The error goes away if I switch to poll. On the backend IMAP server I see that the login was successful. The error occurs when I try to retrieve an email or get a folder listing via IMAP after logging in successfully...

When we upgrade our kernels from 2.6.32.2 to 3.2.16 something strange has happened. On high traffic dovecot/auth looks like not responding. We found a lot of this lines at the log: dovecot: pop3-login: Error: net_connect_unix(pop3) failed: Resource temporarily unavailable (...) and clients stop authorizing Some other errors follow in the wake of: dovecot: pop3: Error: Raw backtrace:

Hello, I'm using samba 4.7.3 to run an AD and I'm currently having issues with the MIT kerberos because it stops some time after starting (and apparently working correctly) without logging nothing out of the ordinary. My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which we're migrating from) and the one I mentioned in CentOS 7 (which will be the only DC in the future).

Hi, Can't find any notes about this in documentation. Is replication supposed to work between different versions of dovecot? I've just found that dovecot 2.2.33.1 was uploaded to debian unstable and it crashes on every replication with older dovecot 2.2.27. (version 2.2.32.1 was probably ok) Summary: - 2.2.33.1 crashes when replicating from/to 2.2.27 - 2.2.32.1 probably ok when

When in the process of testing out the 2.3.0 version of Dovecot, we noticed that on a busy server, imap-login can sometimes take 100% CPU and remain there indefinitely. We grabbed a gdb trace while it was happening: dovenull 36053 31.2 0.0 60460 17316 ?

Linux kernel only supports logical block sizes which are power of two, at least 512 bytes and no more that PAGE_SIZE. Check this instead of crashing later on. Note that there is no need to check physical block size since it is only a hint, and virtio-blk already only supports power of two values.

I'm running Dovecot as proxy in front of some IMAP/POP3 Dovecot & Courier-IMAP servers and in the last couple of days I've been seeing a lot of imap-login crashes (signal 11) on both 2.2.18 and 2.2.25, all SSL related. The following backtraces are taken running 2.2.25, built from source on a test system similar to the live proxy servers. OS: CentOS 6.8 64bit Packages:
