In a special circumstance, FairCom Server's automatic recovery failed with an L69 error. CTSTATUS.FCS showed this message before the error:
WARNING: zero log-entry file handle (tfil)
Transaction-controlled files are assigned a zero transaction file number until it is assigned a transaction file number. If a checkpoint includes that file in its list of open files, it can cause automatic recovery to fail due to the zero transaction file number.
The checkpoint now checks if the file has a zero transaction file number when determining if the file is to be included in the checkpoint's list of open files. If the transaction file number is zero, the file is not included in the checkpoint.
