Hello Moritz and Erich,

the data type is not the only limit.
Function Sequence::getNext is part of the HylaFAX source code.
In util/Sequence.c++ you can see the real limit MAXSEQNUM
which is defined as 999999999 in config.h[.in]

If I understand the code correct, the highest possible value is  
MAXSEQNUM-1. When the file contains this value, function getNext will  
set the new value to 0 with NEXTSEQNUM, which is defined as (((x)+1) %  
MAXSEQNUM). The next call to getNext will change this 0 to 1 and print  
a warning.

In order to avoid this warning and to allow MAXSEQNUM as maximum value  
the macro could be changed to
#define        NEXTSEQNUM(x)   (((x) % MAXSEQNUM) + 1)
