Goal

DESCRIPTION:

Customer reported that he had a failure in his system and when the system restarted some of his groups restarted on
servers that were not defined as backups in his config file.
I had the customer perform a tmuloadcf on the tuxconfig and the output listed backups for groups that did not have
backups defined in the ubbconfig file.
I was able to replicate this behavior and the test case can be found in /nfs/home4/tfrazier/cases/196656.
In an effort to narrow down the root cause I took the following actions followed by unloading the tuxconfig file and
reviewing the output:
1. removed the backup machin from the MASTER variable in the config file. - same result
2. removed the MIGRATE option from the OPTION variable - same result
3. removed the backup machine value from the each DEFAULT arg in the file and none of the groups reported having
backups in the unload file.
4. Added a backup machine to a groups DEFAULT value and the unload file reported that all groups after that had the
DEFAULT values backup server
    for a backup machine even if there was no backup defined for the group.

It appears that if a default value is defined as:
DEFAULT:
        TMSCOUNT=2      LMID=host_gdb001, host_gdb002 TMSNAME=TMS
gdb_001                 GRPNO=100

and then a group that follows this group in the config file i.e.
DEFAULT:
        TMSCOUNT=2      LMID=host_dq002 TMSNAME=TMS
out_002                 GRPNO=340

Notice that there is no backup LMID defined for this group, the tmunloadcf shows that this group has the previous
groups backup LMID value 'host_gdb002' as its backup as well.
It appears that thlmid values are not being handled properly.
