Everything is working fine, but I find something strange that when I execute a statically-linked binary through NFS mounted directory. It will gives me an illegal instruction error or SIGSEGV. If I run it again, the binary can run without problem. I have to reboot or drop all the vm cache in order to reproduce the error again. Also, if I run the binary in harddisk or dynamically link the binary, no problem will be found. Any suggestion to debug this problem? Thanks. Jacky
