Hi,
Everytime I try to cmkdir a directory, the process hangs and consumes all
of the cpu. Here are some details along with the output of top and the
output of strace on cmkdir.
o RedHat 5.0 w/ patches
o Kernel 2.0.33
o cfsd starts okay and registers with the portmapper:
[beldridg@tool2 beldridg]$ /usr/sbin/rpcinfo -p
program vers proto port
100000 2 tcp 111 rpcbind
100000 2 udp 111 rpcbind
100005 1 udp 635 mountd
100005 2 udp 635 mountd
100005 1 tcp 635 mountd
100005 2 tcp 635 mountd
100003 2 udp 2049 nfs
100003 2 tcp 2049 nfs
1092830567 2 udp 3049
o the /crypt directory is mounted (I have also tried specifying nfsvers=2
and to use udp):
[beldridg@tool2 beldridg]$ mount
localhost:/null on /crypt type nfs (rw,port=3049,intr,addr=127.0.0.1)
o top:
PID USER PRI NI SIZE RSS SHARE STAT LIB %CPU %MEM TIME COMMAND
1359 beldridg 20 0 344 344 280 R 0 92.4 0.7 3:50 cmkdir
