SQLException: XA error: XAResource.XAER_PROTO start() - weblogic 10.0.1.0

Question

Hello all,
We are facing java.sql.SQLException: XA error: XAResource.XAER_PROTO start() in one of our EJB classes.
It is only occurring intermittently! Probably during peak load time (not really sure).
Our EJB uses CMP transactions and the EJB operation's trans-attribute is <trans-attribute>Supports</trans-attribute>.
Google is showing similar experiences from users with wls8.1 versions. Has any one come across this error in wls 10? Any help is hugely appreciated.
with Thanks
Val
