similar to: Dovecot proxy: Too many open files

I have a Dovecot server set up as a proxy and getting a ton of these errors, but I'm not sure where to begin troubleshooting it. I'm hearing frequently that Outlook users who use IMAP with SSL are getting disconnected often as a result. Any suggestions?...

Hi all, We moved our Dovecot installation first of all to have all folders and inboxes on NetApps via NFS (with indexes local) then from a physical Solaris 8 4-way UltraSparc server running Dovecot 1.2.5 (32-bit) to a virtualised Ubuntu 8.04 64-bit server with a single virtual processor (in VMWare ESX 3.5) running Dovecot 1.2.8 (64-bit). Since the change, many of our users have experienced

Hi, I have test dovecot on one of my pop3/imap proxies (from rc10 to rc15). I immediately get a lot of error messages like this one : Nov 27 15:10:45 mproxy1 dovecot: pop3-login: file client.c: line 423 (client_unref): assertion failed: (client->destroyed) Nov 27 15:10:45 mproxy1 dovecot: child 21677 (login) killed with signal 6 A lot means one every 2 or 3 seconds. Any suggestion ?

Hi, I'm working for tuning a busy cluster of dovecot servers. Heach server as 4 core, 8GB of RAM and provide POP3 and IMAP access to mailbox. OS is Debian 6.0 and dovecot version is 1.2.15. I am unsure how to set "login_max_processes_count" and "login_max_connections" for reach the best situation when login_process_per_connection is set to no. I don't know what

Greetings - We are running Dovecot 1.1.11 on our servers and have been gradually migrating people off our old (UW-based) systems onto the new (Dovecot-based) ones. As a result the new systems are seeing more connections from more people. We have started seeing problems reported by users of our webmail service that they are getting an error indicating the webmail software (Prayer) has failed to

Hi, Thank you for pointing me about -xc99 flag, I have compiled and installed dovecot inplace of version 1.0.5 without any special actions on the upgrade. And after starting it immediately got in it's log file messages like: --- dovecot: Oct 16 23:10:18 Error: IMAP(seriv): file_set_size() failed with index cache file /var/spool/imap/seriv/.imap/.git-altlinux-ru/dovecot.index.cache: Invalid

I'm currently runing UW-IMAP (compiled vanilla) with procmail and mbox and am making my usual careful crawl (at turtle speed) through figuring out DC config. Some questions: a) I have something like 3-4 root imapd sessions so I presume that the default *login_processes_count* = 3 will be OK. I'm less clear about login_max_processes_count and login_max_connections = 256. A common

Hi, Im using dovecote as my IMAP interface. However i do have a lot of imap instances. its only 7 user using the system as i get this. please advice. 1230 ? S 0:00 imap-login 1309 ?

When running Dovecot (rc6 CVS dovecot-20060808) as a proxy, why would it log the following when it has not yet maxed out the allowed number of imap-login processes?

From netstat, the server has 650 proxied IMAP connections and 450 proxied IMAPS connections, there

http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz http://dovecot.org/releases/dovecot-1.0.rc6.tar.gz.sig Back to rc1's SSL proxying code with some improvements, which hopefully now makes everyone happy. I'm seeing all kinds of problems with namespace prefixes and LIST code. I guess it would be important to fix it before v1.0 since it makes upgrades from other servers easier.. I also

Greetings - I've now got as far as playing with the imaptest10 test utility to see if I can stress-test our development server. imaptest10 is built against dovecot-1.0rc28 It may just be that I'm excessively heavy handed, but when I let imaptest10 rip with the command... ./imaptest10 user=test%03d host=testserver.imap.york.ac.uk clients=50 mbox=./dovecot.mbox msgs=1000 secs=30

Hi, It happens when I try to convert this config (with the dovecot 2.0 beta4 release) : test-mail:/tmp# dovecot -n -c ./dovecot.old.conf # 1.2.11: ./dovecot.old.conf # OS: Linux 2.6.26-2-686-bigmem i686 Debian 5.0.4 log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot_info.log protocols: imap listen: 127.0.0.1:30143 disable_plaintext_auth: no login_dir: /var/run/dovecot/login

Anyone running Dovecot on Solaris, requiring only SSL connections, and servicing thousands of simultaneous users? Our past attempts to do so have failed due to dovecot-auth using up all 256 of its file descriptors. I say 256 since we are limited to that by the 32-bit libraries. We are looking at either compiling Dovecot in 64-bit and letting dovecot-auth file descriptors accumulate (not ideal),

I'm running Solaris 9 Sparc with Dovecot alpha 5 and using maildir format.. I noticed in the log file the following error: dovecot: Dec 20 15:54:18 Error: imap(xxxxxxxx): open(/export/home/xxxxxxxx/mail/.Sent Messages/cur/1135013649.002916.mbox:2,Sab) failed: Too many open files I called the guy and asked him what he was doing... synching his folders. It hung for a while but finally

Hi to all. I upgraded my dovecot from rc5 to rc6. Prior to upgrading, it was working seamlessly. But now I couldn't start dovecot.

Hi, I hope someone can point me in the right direction here. I am migrating a mailbox from a non cPanel server, and the mailboxes have folders which seem to be at the same level as the Inbox. The users access these mailboxes using IMAP. The new server configuration is Exim > Dovecot 1.2.17 > Maildir with the standard cPanel install settings. dovecot -n output below I have created the new

Hi using dovecot 1.0.10 with pop/imap, using maildir, with 2000+ users mostly using pop but many using imap. Once in a great while I have problems with dovecot pop timing out. If I telnet to port 110 it just takes forever to come up or it doesn't at all, the samething happens on the imap port although 110 is always worst. At 1st when troubleshooting I was not sure what was causing the
