Yes, the default is 256, IIRC. That corresponds to 1 GB of KVA, and you have only 1 GB of physical memory to back it. I take it this is a very busy machine. Short of getting more memory, you can decrease memory utilization by the network, e.g. by decreasing TCP window sizes, or you can limit memory usage by the network so you don't get panics. I forget the details here, so perhaps someone else can fill them in. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
