Hi! I encountered this error while upgrading 3.0 to 4.5.3:

Code:
ERROR 1005 (HY000) at line 2: Can't create table './mboxgroup67/#sql-515e_1f1.frm' (errno: 150)
Error while running '/opt/zimbra/bin/mysql --user=zimbra --password=SAoo20h4bjrUQusGVKJZ5cQJ8C --database=zimbra --batch --skip-column-names'. at /opt/zimbra/libexec/scripts/Migrate.pm line 220,  line 94.
Tue Mar  6 11:40:50 2007: Script failed with code 1 - exiting
UPGRADE FAILED - exiting
What should I do?

One more thing, at the start up of the upgrade where it shows my current configuration values, it seems that it cant get the value of my LDAPHOST and LDAPPORT configuration as shown below:
Code:
Setting defaults from saved config in /opt/zimbra/.saveconfig/config.save
   HOSTNAME=stiimail.stii.dost.gov.ph
   LDAPHOST=
   LDAPPORT=
   SNMPTRAPHOST=stiimail.stii.dost.gov.ph
   SMTPSOURCE=admin@stii.dost.gov.ph
   SMTPDEST=admin@stii.dost.gov.ph
   SNMPNOTIFY=yes
   SMTPNOTIFY=yes
   LDAPROOTPW=GBHZs9we
   LDAPZIMBRAPW=GBHZs9we
Is this ok?

Thanks!
