Hi Andree, I've done some additional testing with the suggested change to my-stuff.h, changing the value for:
#define MAX_TAPECATALOG_ENTRIES 4096 ///< The maximum number of entries in the tape catalog ...to 8192. For my purposes, the issue I've reported is resolved between the two parameter changes. Thanks for your guidance in dealing with this issue.
