Hi,
I'm experiencing some problem of syncache (probably).
We have a NFS server which exports everyone's home directory, and I'm
developing my Qualnet code on another machine (NFS client) under my home
directory. However, when I make my code, linking takes extremely long
time (it takes more than 5 minutes while on my laptop it only takes 15
seconds). I examed the /var/log/messages on the NFS server and it was
like this:
May 6 19:51:49 raptors kernel: TCP: [131.179.96.24]:985 to
[131.179.96.25]:2049 tcpflags 0x10<ACK>; syncache_expand: Segment failed
SYNCOOKIE authentication, segment rejected (probably spoofed)
The above message appears every time I make my code ( and only when I
make my code). I turned on linux binary compatiblity on the NFS client
because Qualnet needs to be run in that mode.
Here are some more details: both the NFS server and client are amd64
machines. The server has 8 cpus and the client has 16 cpus.
Any one can help me out? Thanks!!!
Zhenkai
