Hello,
I have dovecot installed and it works for about 3 hours then I get this error (in /var/log/maillog):
Jan 8 08:42:53 stu dovecot: auth(default): pam(grossmsm,69.131.100.47): pipe() failed: Too many open files
I set pam_limits.so to allow the user 'dovecot' to have 8192 open files, and I also changed:
login_process_size = 512
However, it still wont work for more than a few hours. When I run:
lsof -p ps -o pid= -C dovecot-auth
I get:
[...] dovecot-a 1385 root 248u sock 0,5 374241289 can't identify protocol dovecot-a 1385 root 249u sock 0,5 374241391 can't identify protocol dovecot-a 1385 root 250u sock 0,5 374243642 can't identify protocol dovecot-a 1385 root 251u sock 0,5 374241701 can't identify protocol [...]
And the number followed by a u keeps growing. As of writing this email that number is now at 274u. Is dovecot not closing its fd's or something?
