Hello Everyone,
I am observing the following error in couchbase report.log. Can anyone help
me understand what this error is what is the problem here if there is one.
I have also observed lot of crash report getting generated when I stop the
couchbase. Even when I start I see some crash reports related to
compaction. Could you please help me understand this behaviour.
