I have a feeling that it is caused by problems in the SLIP code erroneously expanding bad CSLIP headers. Switching to PPP only stopped the problem completely. The CSLIP problem has been fixed in 2.1.5 by David Greenman, which is why I'm surprised you are still suffering. Try switching everyone possible over to PPP and see if that reduces the problem. DG, did however express doubt as to the cause of my problems, and suggested that I was running out of mbuf clusters. Try rebuilding a kernel with options "NMBCLUSTERS=2048" (4096 etc) or options MAXUSERS 64 Danny
