I am working on a HP-UX machine using JNDI to do some queries against a LDAP directory. In my finally block, I am using a call to dirCtx.close(); On Windows machines (several different flavors) and Linux, this works as expected. However on the HP-UX, this causes the current thread to hang right at the call to close() . Has anyone experienced this, or have an idea what might cause this? thanks... mark
