Hi,
if I set rpcbind_flags="-l" in my rc.conf the machine boots only until
the start of mountd. Then there is a massive worload off the HDD and
after a lite time the console ist spammed with the following message:
"kirk kernel: kern.maxfiles limit exceeded by uid 0, please see
tuning(7)."
I tried to raise kern.maxfiles in single user mode without success. At
19920 mountd and nfsd were able to start, but then i got a panic. See
below for the backtrace.
With kern.maxfiles=10000 I reached another limit. It was something like
"maxprocs exceeded, please see tuning(7)."
I got another panic as I booted in safe mode. The backtrace is nearly
identical to the form the other panic.
The System is 5.2.1-RELEASE-p9.
Excerpt from my rc.conf:
nfs_server_enable="YES"
nis_server_enable="YES"
rpcbind_enable="YES"
#rpcbind_flags="-l"
rpc_lockd_enable="YES"
rpc_statd_enable="YES"
nisdomainname="hochpass"
nfs_reserved_port_only="NO"
portmap_enable="YES"
And finally the backtrace:
