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?
