[Phamm] major catastrophe using phamm

[Don Beaulieu]

I’ll try to explain this in as much detail as possible…


I was removing a user from one of our email alias lists by request and when
I went to delete the user the server hung up on me.

At this point, the server stopped sending and receiving email. I did a
reboot of the system and the server got hung up on the LDAP service.

I then tried an interactive start up and bypassed the LDAP service and the
server booted up, but without he LDAP service running it cannot do
verification, hence, no email send or receive. I then tried restarting the
service manually and it just hangs.

The message I was getting at boot time when the service hangs is as follows:

Checking configuration files for slapd: bdb_db_open: unclean shutdown
detected; attempting recovery.

Bdb_db_open: Recovery skipped in read only mode. Run recovery if errors are
encountered.


I ran the recovery command and it appeared to complete okay but I was still
having problems running LDAP.


LDAP will not start. I cannot access phamm using the admin account, users
cannot login or authenticate.


Other information:


I think the ldap database log file is half missing. The way I read these two
lines:

 > Checking configuration files for slapd:  bdb(dc=vymac,dc=com): file  >
id2entry.bdb (meta pgno = 0) has LSN [1][8654335].
 > bdb(dc=vymac,dc=com): end of log is [1][4401812]

Makes me think the log file is supposed to go to 8654335, but only goes to
4401812. I think thats really bad.

When I run slapd_db_recover in catastrophic recovery mode, it segfaults.


The number of ldap backups available seems to be rather poor, I only see a
copy from May of 2007. I guess that's better than nothing, but it's still
probably way out of date.

I’m currently googling this problem, but any assistance you can provide is
greatly appreciated. If necessary, you can reach me on my cell phone at

Thanks
