I have a Karaf 4.2.4 distribution.
I find that when I drop a kar file into the deploy folder there is a
constant long delay first while the changes to perform for the feature
dependencies are identified and then while the changes to perform to
complete the install of the kar's feature.
I dont see anything in the log to indicate waht is happening but do know the
processor is heavily used during these delays.
Any advice on how I can investigate this?
Example log snippet follows - see the delay from 11:24:13 - 11:24:54 for
"adding features" - "changes to perform". Also the delay from 11:24:54 -
11:26:14 for "done" - "changes to perform":
