Hi Chen,

thank you for reporting this issue. You've triggered a memory leak in
the rm_session interface. Whenever, a thread is bound to a rm_session a
Rm_client object is created within the rm_session. By now, these
Rm_client objects were only destroyed when the rm_session got closed and
not when a thread got destroyed. We commited a preliminary fix in our
public subversion repository. Please, give it a try.

Regards
Stefan
