smbd dead but pid file exists

[Jeffrey O'brien]

This issue came up after a power event, samba just stopped working.  All other services are running as expected.  Samba was upgraded from 3.0.25b is hopes to fix the issue with no avail.
Current Version Info:
samba-common-3.0.28-0.el4.9
samba-3.0.28-0.el4.9
Kernel:  2.6.9-78.0.13.ELsmp #1 SMP
CentOS 4.7

Service Output:
service smb start
Starting SMB services:                                     [  OK  ]
Starting NMB services:                                     [  OK  ]

service smb status
smbd dead but pid file exists
nmbd (pid 21422) is running...

Logs aren't giving much useful information, I also changed the log level from 1 to 5 with nothing sticking out abnormal.  The debug output shows loading everything fine from parsing the smb.conf, share definitions, character sets, locale, printers.

Around the time of the issue these started showing up in the logs: (/var/cache/samba/ntprinters.tbd): tdb_rec_read bad magic,  google-foo shows this as a harmless annoyance.

  tdb(/var/cache/samba/ntprinters.tdb): tdb_rec_read bad magic 0x42424242 at offset=4520

Has anyone seen this, got some useful hints to nail down where this is blowing up or a workaround?

Thanks,
Jeff
