Postfix and sasldb2

[foxb]

I found following error in the log:

Code:

sasldblistusers2: unable to open Berkeley db /var/spool/postfix/etc/sasldb2: Bad file descriptor
sasldblistusers2: _sasldb_getkeyhandle has failed
saslpasswd2: error deleting entry from sasldb: DB_NOTFOUND: No matching key/data pair found

Is that normal or I missed something in installation process?

in addition I have these too

Code:

postfix/smtpd[28337]: fatal: No server certs available. TLS can't be enabled
postfix/master[14108]: warning: process /usr/libexec/postfix/smtpd pid 28337 exit status 1
postfix/master[14108]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling

I'll add this one too it might be relevant

Code:

/usr/lib/chkrootkit-0.48/chkrootkit: cannot make pipe for command substitution: Too many open files in system
/usr/lib/chkrootkit-0.48/chkrootkit: fork: Cannot allocate memory

Thanks in advance.
