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 ?
Depends on how many logins/sec you have. It's normal if you have >400/s, but probably not otherwise..
It's less than 400 login/s. I found that there were an increasing number of login processes (about 500 extra processes per day). In the web archive there is a similar posting (but no answer): http://dovecot.org/list/dovecot/2005-February/006238.html
I tried to fix it using the login parameters. Currently we use login_process_per_connection=no which gives much less extra processes (approx. 100 per day).
