Why am I getting exceeding maximum number of connections or AUCL errors?
This error is most commonly caused when a newsreader attempts to open a new connection before it has completely closed a previous connection. If your news reader attempts to open 11 or more connections for standard account holders (or 21 or more connections for 256 Bit SSL Enabled members), you may see an error message that includes the phrase “exceeded limits on aucl”. This stands for Authorized User Connection Limit. If you see this message, just wait for a task to complete before starting the next. As an example, sometimes this occurs when all of your potential connections are being used and you attempt to download headers. Downloading new headers opens a new connection, and if none of the active connections are available, you will receive errors until one is available. The only other workarounds are either lowering your maximum connection limit in the newsreader’s settings, or trying a different newsreader.
