I'm running FreeBSD with 2 NFS mounts over tcp, apache 1.3.31,
openwebmail(read/write on both nfs mounted filesystems, /var/mail
spooldir and webmail userdir) and proftpd.
# uname -a
FreeBSD 5.2.1-RELEASE-p8 #3: Mon Jun 28 07:18:32 BRT 2004
src-all last updated at: Sat Jun 19 09:28:59 BRT 2004.
The problem occurs only when users access the openwebmail,
reading/writing data on nfs mounted filesystems.
Here my sysctl.conf:
net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1
vfs.nfs.access_cache_timeout=60
net.inet.ip.check_interface=0
net.inet.tcp.inflight_enable=1
net.inet.tcp.inflight_debug=0
net.isr.enable=1
kern.polling.enable=1
kern.polling.user_frac=50
EOF
... and here part of my kernel config file:
machine i386
cpu I686_CPU
makeoptions DEBUG=-g
makeoptions NO_MODULES=yes
options NFSCLIENT
options NFSSERVER
options QUOTA
options COMPAT_FREEBSD4
options KTRACE
