Description

Hi, I've been using ApacheDS since version 1.5, and I'm running into this issue: the system runs ok for days, or weeks, until I get this error in the logs:

 

[20:00:03] WARN [org.apache.directory.server.ldap.LdapProtocolHandler] - Unexpected exception forcing session to close: sending disconnect notice to client.
java.lang.StackOverflowError
 at org.apache.directory.api.ldap.codec.factory.SearchResultEntryFactory.encodeValues(SearchResultEntryFactory.java:66)

 at org.apache.directory.api.ldap.codec.factory.SearchResultEntryFactory.encodeValues(SearchResultEntryFactory.java:68)

After this error the search operations are really slow, up to the point that searches that took few ms take more than one minute. I'm unable to reproduce it, please help.
