The sizing of FML buffers appears to be incorrect for buffers that are received by services.
For example,  SVC1 receives an FML buffer, allocates a new bigger buffer based on the size of the received buffer
(i.e., info->len), tpcalls SVC2, then tpreturns.  Subsequent calls to SVC1 reuse the bigger buffer allocated by the
previous invocation.  Thus, a sequence of calls to SVC1 results in increasingly larger buffers being allocated, even
though the client passes buffers of the same size.  Eventually the SVC1 process runs out of space.
