 I'm going to guess at what is happening here.  You have a *PSSR routine to
do processing for the timeout condition.  When getting those line errors,
the program goes into the *PSSR.  What is probably going on is that the
timeout occurs during error processing, creating an error upon error
condition.  

 I think the solution is to explicitly test for those error conditions in
your subroutine.  Maybe you should post the pgm code?
