RE: [SQU] Authentication error/ odd behaviour

Whats the last response from the script before it gets marked as busy?
(You may need to turn debugging up). Does it complete it's last request?
I don't know the innards of bash, but if there is any read/write caching
on the requests, you would experience the issues you describe here.
