> In troubleshooting.adoc, as well as in the error message when we fail to hole punch, we suggest using the file block manager as a workaround. It says something vague about "at the cost of some scalability and efficiency" but should be something a lot more ominous -- users are quickly running out of file descriptors if they try the FBM.
