EventLog Analyzer service pack update failed due to database corruption

EventLog Analyzer service pack update failed due to database corruption

Hi,

While trying to follow the upgrade path detailed here ( https://www.manageengine.com/products/eventlog/service-packs.html) from 11000, the application of service Service Pack 11.0 (SP-11.0) failed with a database corruption error. I followed the backup procedure detailed here ( http://kbase.eventloganalyzer.com/how-do-i-take-backup-for-ela#). The version that we have installed is 11072.

Here is the wrapper when trying to restart services:

Can you let me know how this could have happened even though the service was stopped?

Thank you.
