About 5 years ago my LISTSERV went into a loop and ate 4h of CPU time because the RECEIVE command goes into a loop if you present it with an invalid file in Netdata format. I called the support centre and they said I should send them a copy of the disk file causing SENDFILE to generate such an invalid spool file, and they would fix SENDFILE, and added that RECEIVE does not need fixing. I said the problem is not with SENDFILE, the file came from a machine on the network running Multics. I was told the problem does not exist then, and if I insist on getting an APAR it will be closed WAD because RECEIVE was never meant to support incoming files from non-supported operating systems.
