This error according to the logs is caused by a 5-year old Perl script

  • 0

This error according to the logs is caused by a 5-year old Perl script that merely grabs data from MySQL via a simple SQL select and displays it.

It’s running on my dev machine which is MBP with 8GB of RAM running the stock Apache.

Once a while, once or twice a month, I get the following error for no apparent reason :

panic: memory wrap at /System/Library/Perl/5.10.0/CGI.pm line 4001.

Apache refuses to run the script again and only a reboot of the OS would make Apache relent. The OS says that there’s 3+ GB of free memory when it happens so it’s not a low memory issue. Luckily this doesn’t happen on the production Debian 5 server.

What’s a memory wrap? And what causes it?

    I hit this bug as well in a slightly different circumstance. PerlMonks, as ever, has just saved me probably days of work:

    http://www.perlmonks.org/?node_id=823389

    the problem lies in the way osx ties
    up other resources. a simple sleep
    will give the os time to close and
    open. restart or graceful will go in
    conflict.

    apachectl stop
sleep 2
apachectl start
