Comment (by verycoldpenguin@…):

 Here is output (with patch2 incorporated). The information displayed is
 the number of lines entered into the strlist array, which is used to
 determine the filesystem info. The filesystem info is ordered information
 (directory, hostname, etc. etc.) one item per line. This means that 8
 lines should complete 1 record. For my system, the correct response for a
 running slave backend should be 48 items. 32 items occur if the backend
 was not contactable. The 81 demonstrates 11316 I believe.
