Dealing with 509 Bandwidth Limit Exceeded errors
October 6th, 2009
“509 Bandwidth Limit exceeded error” occurs when the bandwidth allocated to an account exceeds.
At that time the cPanel creates an empty file by that domain name in the /var/cpanel/bwlimited directory.
To view such sites please do the following
1) Go to the /var/cpanel/bwlimited directory
2) And remove the file which has name of his domain or subdomain .
But see to it that you touch those files again and ask the client to purchase additional bandwidth.
