Problem: Postfix not starting after upgrade from UCS4 to UCS 5

[Daniel_Duchon]

Problem

After Upgrading from UCS4 to UCS5, postfix isn’t starting anymore.

Environment

The Variable mail/postfix/ldap/timeout has the value mail_postfix_ldap_timeout:

root@example:~# ucr get mail/postfix/ldap/timeout
mail_postfix_ldap_timeout

Solution

There might be situations where the variable is filled with a non integer value. In this case, set it to a normal integer back and restart postfix afterwards:

root@example:~# ucr set mail/postfix/ldap/timeout=15
