folks I am working in a project called process scheduler and the intention is to run processes parallely.We are using using a pre-forked server model to do this.We use the DB_file(with DB_filelock) to a file and the forked children will read the values from the file to run the job.(The forked process will run the job and write the status of the job into one more file).The process works fine except I get an error "cant call seq on an undefined variable",when I read the status file.I also tested the program to check and make sure that locking is not a problem.This I did it by running the same program (that the program which access the same file in a loop) and I could see the program to finish with no issue.If you have come across this problem,please let me know. Thanks Kris
