Description

When systems are exchanging data and one of them is waiting, the connection will be displayed as "WAIT" in netstat. In such case it's up to the systems to decide how long they want to keep the connection open, for possible new data. Too much waiting connections might have a bad influence on new connections, as the kernel needs to maintain a long list. If this control shows up, it's usually a matter of determining if the behavior is common and if related applications need to be fine-tuned.
