David,

Please could you rerun with the following debug patch.

http://oss.oracle.com/~smushran/.dlmglue/0001-ocfs2-Patch-to-debug-hang-in-dlmglue-when-running-dl.patch

May make sense to fire it either later in the day or fire mlocate
a shortwhile after starting the test. That's to reduce the trace logs.

Thanks
Sunil
