Hi, all.
I just upgrade from 1.0.15 to 1.1.1 in a test box(RHEL 5.2, x86_64).
after upgrade, i got this warning msg:
----8< ----
# /etc/init.d/dovecot restart
Stopping Dovecot Imap: [ OK ]
Starting Dovecot Imap: Warning: fd limit 1024 is lower than what Dovecot
can use under full load (more than 1280). Either grow the limit or
change login_max_processes_count and max_mail_processes settings
[ OK ]
----8< ----
but i changed either login_max_processes_count and max_mail_processes
to 2048, it raised the same msg. How can i solove this issue?
Thanks very much.
My dovecot -n output:
----8<----

How can i solove this issue? >I'm just guessing - but reading that warning it appears to me that Dovecot is saying that as it is configured, it can consume more O/S resources (I assume fd is "file descriptors") than the O/S is currently configured for. So you need to DECREASE your dovecot max processes to decrease the (potential) system demands - or increase your O/S settings. Daniel
