same parent node update in different thread

We are trying to add nodes under the same parent node in different thread.
We got the below warning.

WARN  org.apache.jackrabbit.core.session.SessionState   : Attempt to perform
node.addNode(abc/XXX/XXXX, mgnl:content, null) while another thread is
concurrently writing to session-admin-187. Blocking until the other thread
is finished using this session. Please review your code to avoid concurrent
use of a session. 

is there anything i need to watch out for this warning?

Yes. Sessions are not guaranteed to be thread-safe, so you should use
a separate session for each thread or alternatively explicitly
synchronize access to a shared session.
