joeg0812 has asked for the wisdom of the Perl Monks concerning the following question:

Started getting this error below after a power failure. Have restarted all the procedures that I know, but can't get into my stuff. Maybe someone can decipher what is going on. Any help would be greatly appreciated. Not a tech guy.

    First off this is not the Apache administration forum. Some sort of bad-juju happened to your Apache infrastucture and you need to work with your admin to sort it all out.

    That said, with the contextual information you have provided there still isn't much to work with here. 

    my $session = shift;

    Where is this coming from? Is the MySQL database hinted at by the raw error dump up and running and sane? What's in the error logs for the server?

    It is not a perl-error. Your script died because the supplied session data is not in the correct format (it is probably empty or NULL), hence line 40 was triggered and that just died your script. It is actually a safeguard to protect against invalid session data, so Perl may have saved you from worse.

    That being said, we cannot see what caused this invalid session data: it might be a filesystem or database problem. Some network or DB-admin needs to look into it.

    Another possible "solution" is to delete all cookies for this site on your client PC and log-in again. It may reset your session and issue new session data that allows you back in. It will not solve the fact that probably your database now contains some rubbish data you may have to delete manually.

    A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

    If things went weird after a power-failure then what probably happened is that the filesystem on the disk is bonkers and hasn't been repaired and therefore by now is probably far worse.
