Connection failure between argonaut-server when we search a package

Hello,

When we edit a package class and ask to make a search in the list we have a connection failure. I search "slapd" to test this issue.

 Communication failure with the infrastructure service! 


But the search work well and I can add my new package without any problems.

Cheers.
