This is scaled # by approximately 2048 bytes. The system will auto-size the mbuf area # if this options is not specified or set to 0. # options NMBCLUSTERS=1024" I had no provision at all, but changed it to "=8192" which is a wild guess only since the "auto-size" wasn't adequate. Anyone with additional tips.....??? Best regards, Jack L.
