asynch descriptor resize wait event

Anyone know what is causing "asynch descriptor resize" wait events on
11gR2.(11.2.0.1)..on a test database which is mostly idle?
Linux RH 4 - 64bit
 
I can only find a limited amount of information on MOS and hardly
anything in the Internet.
 
 Hanging in SQLPLUS when querying dba_autotask_client which led me to
search for wait events.
 
thanks
