forrtl: severe (36): attempt to access non-existent record, unit 11

Hello Team,

When we run this script

./get_tmpa.sh 2008010106 2008010106

than I am getting following error:

forrtl: severe (36): attempt to access non-existent record, unit 11, file /iitm1/sspm-res/ocn/deepa/gfsletkf/trunk/gfs/run/tmp/gfs-letkf_deepa_exp1_get_tmpa/tmpa.dat
