Looks like the problem below is caused by this commit:
dwmalone 2001/10/04 06:11:48 PDT
Modified files:
lib/libc/rpc clnt_vc.c svc_vc.c
sbin/mount_portalfs activate.c
sys/kern uipc_socket.c uipc_usrreq.c
sys/netgraph ng_socket.c
sys/sys domain.h un.h
usr.sbin/ppp bundle.c
ACPI, which I previously wrongly blamed, isn't involved in any way. Right now I
am running a very recent -CURRENT, modulo this commit and more recent commits to
the same files, i.e. I updated using:
# cvs -q -R update -A -P -d
# cvs -q -R update -D'Oct 04 15:11' kern/kern_proc.c kern/kern_prot.c kern/uipc_socket.c kern/uipc_usrreq.c netgraph/ng_socket.c netinet/ip_fw.c netinet/raw_ip.c netinet/tcp_subr.c netinet/udp_usrreq.c sys/domain.h sys/socketvar.h sys/un.h
All my problems are now gone. This sort of makes sense to me, as the culprit,
qmail, is quite socket intensive.
Anybody has any idea how to properly fix?
Bye,
Andrea

It is easier to fix Unix than to live with NT.
