This is what my script does :

#!/bin/sh

FILE=$1
awk -F "\"*;\"*" '{print ";",$1,";",$2,";",$3,";",$4,";",$5,";",$6,";",$8,";",$9,";",$10,";",$13,";",$15,";",$18,";",$22,";",$24,";",$25,";",$26,";",$27,";",$28,";",$29,";",$30,";",$31,";",$32,";",$33,";",$35,";",$36,";",$38,";",$39,";",$42,";",$47,";",$48,";",$49,";",$53,";",$54,";",$55,";","FILE"}' $1 | sed -e "s/ ; /;/g; s/; /;/g" | mclient -lsql -d demo -i -s "COPY INTO cdrwholesaler FROM STDIN USING DELIMITERS ';' NULL AS ''"

and this is how i call it :

find /usr/ftp -name '*.CDR' -exec /var/www/consolecdr/batch/test_monetdb/awk_csv_generator.sh {} \;


Is there anything im doing wrong ? I have the feeling there must be too many connections crashing the system .. coz after that i can't use mclient anymore, i have to restart the DB.

Please advise,
Thanks
SB
