Hi! Since yesterday I am experiencing big problems when delivering mail to an alias-list. (Yes, I have set up an owner-listname alias. :-))
When delivering mail to a list which is implemented as an ldap-alias-list (currently 289 recipients), the local daemon delivers most of the mails to local mailboxes but then fails to open some .forward files with "Too many open files". (See below.) The mail is then re-queued and fails again at the next queue flush. The number of open files is currently limited to 1024: # cat /proc/$(pgrep master)/limits | grep "Max open files" Max open files 1024 1024 files My number of users/.forward files must have hit a limit, since everything worked fine for the last seven years. Maybe the problem is that the destination address (an-alle) is an alias, which points to the real list (rk)? # postmap -q an-alle /etc/aliases rk # postmap -q "rk" ldap:/etc/postfix/ldap-groups.cf | tr , '\n' | wc -l 289 There are owner-listname aliases for both: # postmap -q owner-an-alle /etc/aliases edvadmin, xyz # postmap -q owner-rk /etc/aliases edvadmin, xyz I'd appreciate any hints to solve or further debug this problem! Thanks, --leo P.S.: I am using postfix-2.5.6. -------------------- 8< -------------------- [...] Sep 21 18:20:05 samba postfix/local[26856]: 1664D3FE6B: to=<a...@klbg.n.roteskreuz.at>, relay=local, delay=5442, delays=5441/0.01/0/1.2, dsn=2.0.0, status=sent (delivered to mailbox) Sep 21 18:20:05 samba postfix/local[26856]: warning: cannot open file /home/XXX/.forward: Too many open files Sep 21 18:20:05 samba postfix/local[26856]: warning: 1664D3FE6B: defer service failure Sep 21 18:20:05 samba postfix/local[26856]: 1664D3FE6B: to=<x...@klbg.n.roteskreuz.at>, relay=local, delay=5442, delays=5441/0.01/0/1.8, dsn=4.3.0, status=deferred (bounce or trace service failure) Sep 21 18:20:05 samba postfix/local[26856]: warning: 1664D3FE6B: flush service failure [...] Sep 21 18:20:06 samba postfix/local[26856]: warning: cannot open file /home/YYY/.forward: Too many open files Sep 21 18:20:06 samba postfix/local[26856]: warning: 1664D3FE6B: defer service failure Sep 21 18:20:06 samba postfix/local[26856]: 1664D3FE6B: to=<y...@klbg.n.roteskreuz.at>, relay=local, delay=5443, delays=5441/0.01/0/2.4, dsn=4.3.0, status=deferred (bounce or trace service failure) Sep 21 18:20:06 samba postfix/local[26856]: warning: 1664D3FE6B: flush service failure [...] Sep 21 18:20:07 samba postfix/local[26856]: warning: cannot open file /home/ZZZ/.forward: Too many open files Sep 21 18:20:07 samba postfix/local[26856]: warning: 1664D3FE6B: defer service failure Sep 21 18:20:07 samba postfix/local[26856]: 1664D3FE6B: to=<z...@klbg.n.roteskreuz.at>, relay=local, delay=5444, delays=5441/0.01/0/3, dsn=4.3.0, status=deferred (bounce or trace service failure) Sep 21 18:20:07 samba postfix/local[26856]: warning: 1664D3FE6B: flush service failure -------------------- 8< -------------------- -- e-mail ::: Leo.Bergolth (at) wu.ac.at fax ::: +43-1-31336-906050 location ::: IT-Services | Vienna University of Economics | Austria
