You didn't post your version but I've seen this on older versions,
especially on SE.
Make sure you 'update statistics' before the dbexport, that usually
helps.

Hi, I exported informix database using dbexport buildin tool.
I have many tables and in same cases there are difference between row
number reported in sql exported file and real number of rows in unl
file:
eg.
{ TABLE test row size = 8 number of columns = 2 index size = 24 }
{ unload file name = test101.unl number of rows = 91425 }
but real number of rows is 91320
While is this?

this is called corruption;
run bcheck, secheck for standard engine on that table
or tbcheck; oncheck for online/ids;
