The reader process is the UNIX Named Pipes Access Module, np_axsmod.so, which tracks data flow and copies inbound data to a fallback data file. If Teradata PT determines it must fall back to an earlier point in the data stream, it issues the standard File Set Position access command to np_axsmod.so, which supplies subsequent reads from the data it saved in the fallback data file.
