I've attempted an upgrade of a Zimbra 4.5.3 to 4.5.6 on an Fedora Core 4 system. I started out well but doesn't seem to get past starting LDAP, i.e. the install process is hanging here (since about half an hour or so):
Checking the processes:
Restoring existing configuration file from /opt/zimbra/.saveconfig/config.save...done
Operations logged to /tmp/zmsetup.log.8971
Checking ldap status
So it looks to me like slapd is not detaching. Looking at what slapd is doing:
# ps -eaf | grep ldap
root 9221 8971 0 21:38 pts/1 00:00:00 sh -c su - zimbra -c "/opt/zimbra/libexec/zmldapapplyldif" >> /tmp/zmsetup.log.8971 2>&1
root 9222 9221 0 21:38 pts/1 00:00:00 su - zimbra -c /opt/zimbra/libexec/zmldapapplyldif
zimbra 9223 9222 0 21:38 pts/1 00:00:00 /bin/bash /opt/zimbra/libexec/zmldapapplyldif
zimbra 9297 9223 0 21:38 pts/1 00:00:00 /bin/bash /opt/zimbra/bin/ldap start
zimbra 9349 9297 0 21:38 pts/1 00:00:00 /opt/zimbra/openldap/libexec/slapd -l LOCAL0 -4 -u zimbra -h ldap://mail.elit-caffelatte.com:389 -f /opt/zimbra/conf/slapd.conf -d 1
root 11282 32621 0 21:56 pts/0 00:00:00 grep ldap
which doesn't tell me a lot, not knowing anything about the internals of slapd, but it clearly is not doing much!
# strace -p 9349
Process 9349 attached - interrupt to quit
futex(0xb3a8fbf8, FUTEX_WAIT, 9351, NULL
also found this thread: Upgrade: 4.5.5 -> 4.5.6 failed, LDAP/slapd issues, which may be related, but while it mentions that the issue was resolved, it doesn't say how!
Any help is wildly appreciated as I'm really not sure what to do next - stop the upgrade and try it again?
