Db2 Database Marked BAD

In a single month, I was forced to face 3 crashes in my productions db. Database is sitting on DB2v9.5.8 32 bit , on a VM. The database has grown recently and when there is a stored procedure is running on a particular table the inconsistency happens.

What the procedure is doing is the following;

insert into DISK_MASTER (host_name,DISK)
select distinct upper(scope.sanitize_hostname(HOST_NAME)),UPPER(ca se when DISPLAYNAME is null then '' else DISPLAYNAME end) from
DISK_TADDM
where host_name is not null and TYPE in('IDE disk','SCSI disk') and in_rollup=0
EXCEPT select upper(host_name),UPPER(disk) from DISK_MASTER;--

the child table got around 2 crore data.

Attaching the error screen shots for expert advice. Now the db2diag.log is flooding with the error
