GC FREELIST



GC FREELIST
wait means, basically you are waiting on the LE (Lock Element) during
the lock acquision.  LE works somewhat (in crude terms) like buffer
hash chains and you can query the X$KCLFX (LE Freelist structure) and
see whether the LENGH is close to zero on the offending node.

A quick fix is to restart the node (if the length is zero on the
troubled node and bigger numbers in the other two nodes) just to clear
the mess in the freelist chain.
