In the process of migrating to Dovecot 1.0beta3, any tips or step-by-step instructions that might relate to Solaris 9. Thanks Bertrand Leboeuf leboeuf at emt.inrs.ca

...es, and particularly if they are running OS X (especially 10.4), and/or have compatible solutions (I've been reading the mailing list quite a bit, and every now and then, I find a solution that just "doesn't work" because of the differences in OS: 1) Too many files open - no plimit command on OS X, so I can't figure out how to increase the max number of open files... Also, are there any alternative means of CLOSING the files? stopping/restarting dovecot didn't seem to help; 2) I was running 1.0beta1 last week, and am now on 1.0beta3, but I'm still not seeing...

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),

...under max. load (256 < 1000), because of default_client_limit It could try increasing the limit first, and only report the warning if that fails. I'm attaching a patch that does just this. Without the patch, the soft fd limit is kept at whatever it was on dovecot startup: % pfexec plimit $(pgrep dovecot) 18737: /opt/niksula/sbin/dovecot resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 1...

..., but that's not quite elegant. - Dovecot is running in a Solaris 9 environment. It turned out that Dovecot crashes when more then 256 filedescriptors are being used. This is rather normal, since Solaris only support 256 descriptors per 32-bit process. After starting Dovecot, I do a 'plimit -n 8192, 8192 `cat /var/run/dovecot/master.pid`, which allows Dovecot to have 8192 filedescriptors. Timo, is it possible to introduce a config file option to configure the number of descriptors? - Pine and Outlook users don't see the adresses or names of the people who sent them email. In...

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

Help! Our students are back and they are pounding my dovecot server to death (ie "Login process died too early - shutting down" or "too many open files" type crash). I've had my third crash today. My setup: Solaris 10, imap and imaps, 3K users coming in via horde webmail. My current connection settings are: login_max_processes_count = 2048 login_max_connections = 4096

...ious problem since I just boosted this level in the /etc/system file). I tried lowering it but keeping it high enough for samba - did not work. Ended up setting the values in the /etc/system file back to the defaults and rewriting the startup script for samba so that it gets a kick in the butt from plimit when it is started so that only samba will be able to allocate the higher number of file descriptors. Titan is back up - all the things I could think of that run on it seems to be happy now and samba has its higher number of file descriptors. I'll log a low priority case with Sun to have them...

Hi samba fans, We run samba on Solaris SunOS 5.8, samba 2.2.2 and are plagued by failing connections for a while. We have about 150 people at max usage connecting simultaneous to 1 samba server, mostly from within Win NT Terminal Server Sessions (this might be related, as these sessions occur from only from four different IP's namely our four TS servers) Symptom: user cannot mount one

...time drives are not mapped. In the log files I can see that it has happened even when we ran version 3.0.10. We run Samba on Solaris and have previously increased both "rlim_fd_cur" and "rlim_fd_max" to 1024. Do we need to increase these values further ? If I do "plimit <smbd process>" it says: resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 8192 unlimited cored...

We've run into a situation where the Dovecot master process "dovecot" runs out of file descriptors on Solaris 10 since the default is only 256: # plimit 1 1: /sbin/init resource current maximum time(seconds) unlimited unlimited file(blocks) unlimited unlimited data(kbytes) unlimited unlimited stack(kbytes) 8192 unlimited coredump(blocks) unlim...

...n = no" with no problems, except more CPU load and needing to increase login_max_processes_count (and strictly speaking the max fds set with ulimit -n would need to be increased, though I didn't do that as it would have involved killing and restarting the master process - come back Solaris plimit!) Just after midnight, I switched back to "login_process_per_connection = no" and set "login_max_connections = 32" and managed to get core dumps enabled, hence the above! Apart from this problem, the virtual machine has been doing extremely well, so it's not CPU or I/O loa...

Hello, a few days ago I switched out UW-server installation to dovecot 0.99.14 (Solaris 9). There were a few client issues, but mostly the migration was ok. But I have still some questions/problems: +) dovecot-auth: ... PAM: pipe() failed: Too many open files I increased the max. number of open files. Is this normal behaviour, that more than 512 open files are needed ? +) we're using mbox
