Connection to LDAP Server wont close

Hello, i am currently trying to setup a Elasticsearch cluster with ODFE.
I was able to configure LDAP for authc and authz. It is was working fine so for but I notices that when performing changes on Roles three new connections to the LADP will open on the client side but the old three wont close. On the LDAP server itself I see several 100 open connections rising exponential when performing role update. I once had over 32.000 open connections on the LDAP.
Does any one else experience this behavior?
