Karaf list command is stuck or hung

Issue

• The Karaf 'list' command hung.
• bundle:list command should return all the listing of all bundles in karaf immediately (at least less than a minute). But it seems the bundle:list never response after few minutes of waiting.

• I have tried same command on another server and it response within less than 10 seconds.

• It seems Karaf bundle list will hang when there are too many bundle (jar) in deploy folders. Current we have more than 80 bundles concurrently running in the problematic server.

• Please note that bundle (jar) are actively running and does not seems to encounter any issue.
