Wee have had a process in place for several years wherein a PC-based server collects console data from TPF systems and, when it has a full buffer, FTPs the data to VM. APPEND is always specified and the file id is date-specific. For 8 years, this has worked without fail. Now, there are times when the append apparently does not work, a new file is created. Normally, all files start with data that is time stamped 00:00:00. The corrupted files start with data time stamped anywhere from 03:00:00 t0 06:59:59. The logs show the usual amount of activity preceding the corruption. Interestingly, the files getting corrupted all come from the same datacenter. Another interesting thing is that it is random - not all files from this center are corrupted. In fact, it is only about 1 in 15.
