Hello Rizza,
From the attached Knldiag log, I see you run into a log IOSequence mismatch problem.
2013-05-04 11:20:17 21 ERR 20048 Log Log_VolumeIterator.cpp:309
2013-05-04 11:20:18 21 ERR 20048 Log 2013-05-04 11:20:17 Log Error 20048

How large is your log volume ??
Workaround for this issue:
-> Perform a complete data backup in the admin state (db_admin)
-> As a backup, just copy the LogVolumes to another location
-> Run "db_execute clear log" in admin state
-> Restart the database online
-> I would recommend to switch the autolog backup on to avoid the log full situtaion in furture.
Also the version of databsae you are using is quiet old one. I would recommend you to upgrade to the latest possible versions to avoid any known issues.
