"allowed" operations in bash read while loop

I have a file text.txt

that contains two lines.

first line
second line

      

        
        
        
      

    

I am trying to loop through in bash using the following loop:

while read -r LINE || [[ -n "$LINE" ]]; do
   # sed -i 'some command' somefile
   echo "echo something"
   echo "$LINE"
   sh call_other_script.sh

   if  ! sh some_complex_script.sh   ; then
        echo "operation failed"
   fi

done <file.txt

      

        
        
        
      

    

When called some_complex_script.sh

, only the first line is processed , but when commented out, all two lines are processed. some_complex_script.sh

does all sorts of things like initial processes, sqlplus starting from WildFly, etc.

./bin/call_some_script.sh | tee $SOME_LOGFILE &
wait

...

sqlplus  $ORACLE_USER/$ORACLE_PWD@$DB<<EOF
whenever sqlerror exit 1;
whenever oserror exit 2;
INSERT INTO TABLE ....
COMMIT;

quit;
EOF

...
nohup $SERVER_DIR/bin/standalone.sh -c $WILDFLY_PROFILE -u 230.0.0.4 >/dev/null 2>&1 &

      

        
        
        
      

    

My question is , if there are any operations that should not be called in some_complex_script.sh

, but in a loop (it can also take 10 minutes to complete, is it generally a good idea?) That could break this loop. The script is called using Jenkins and Publish over SSH plugin . When some_complex_script.sh

called by itself, no problem.
