Hi, Thanks for your reply. added sysctl,
Set the default value's of 4.3 in the kernel. net.inet.tcp.sendspace=16384 net.inet.tcp.recvspace=16384 But still no buffer space messages when pinging a host. Can I try something else? also tried to lower udp.recvspace, but did not help :( But I never had this problem before in other releases, but they changed the IP stack in 4.5 right? grtz, Marcel At 18:29 18-02-2002 +0100, you wrote: >try lowering net.inet.tcp.sendspace and net.inet.tcp.recvspace(kernel, not >interface values), this happened to me when I was experimenting with >considerably high buffer values (such as 128k).
