             Summary: Documentation for how to recover mkahadb
                 Key: AMQ-9186
                 URL: https://issues.apache.org/jira/browse/AMQ-9186
             Project: ActiveMQ
          Issue Type: Wish
          Components: AMQP
    Affects Versions: 5.17.0
            Reporter: Ashish


Hello,

I have migrated my active mq setup to cloud(eks). I am using efs as my persistence layer.
I have been using ignoreMissingJournalfiles="false" and from the past few days i have been seeing the below error. (restart policy is always)

{code:java}
Caused by: java.io.IOException: Detected corrupt journal files. [60:29718101 >= key < 60:33554433]
{code}
In order to fix this I first tried to delete the db.data file and restarted the broker. That ended up in the below error and also ended up in a for loop restart (restart policy is always)

{code:java}
Caused by: java.lang.IllegalStateException: PageFile is not loaded 
{code}
Later i set ignoreMissingJournalfiles="true", which allowed the broker to ignore the corrupt journal file and start the broker. 

What would be your recommendation/steps to address this problem. Are their already any documentation for it?

Note : The broker ends up in this state due to OOM, I have already increased the brokers memory substantially (4gb), I just dont want to increase the memory further without understanding if there is a way to recover the broker 1st. I am also using EFS with Performance mode : Max I/O and Throughput mode : Bursting

Regards
Ashish
