Symptoms

Inserting data into a relational table using an XMLTABLE() construct which passes an XMLType table using the default "store as securefile binary xml" fails with error: ORA-04030: out ofprocess memory when trying to allocate 55600 bytes (kxs-heap-w,qmemNextBuf:Large Alloc).

The issue does not reproduce on 11.1.0.7.

The following code demonstrates the issue (if the number of rows are reduced to 65300 then the error does not occur):
