I've read similar post about such an issue, but have not seen any posted solutions. I have a clean install of Solaris 10 running a Sunfire v440 w/postfix. I am using dovecote solely for SMTP authentication, and it is working just fine except while running top I constantly see:

548 root 1 30 0 5240K 3416K run 522:51 49.45% dovecot-auth

The process never crashes, nor are there any errors. I ran a test devel box with an almost identical setup of postfix and dovecot on Solaris 9 (V240) and the functionality is identical, but with no high CPU usage. The following are my configs and system info:

dovecot --version 1.0.3

OS Solaris 10 Sparc (Patched)

No NFS all local ufs

dovecot -n # 1.0.3: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot protocols: none ssl_disable: yes login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login auth default: mechanisms: plain login passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen client: path: /opt/pmx/postfix/var/private/auth mode: 432 user: postfix group: postfix

cat dovecot-ldap.conf: hosts = localhost

dn = cn=priv-account,ou=container,dc=example,dc=com dnpass = mydnpasswd

ldap_version = 3 base = ou=people,dc=example,dc=com scope = subtree pass_attrs = uid=user,userPassword=password pass_filter = (&(objectClass=posixAccount)(uid=%u))

default_pass_scheme = CRYPT

Any help would be great!!
