Can > you feed the trace to Ethereal and see what it has to say about it? > To test my theory that the -1 times are causing the error because they violate the protocol, I chanded the #define nfsm_v3sattr in /usr/src/sys/nfs/ nfsm_subs.h to use NFSV3SATTRTIME_TOSERVER in stead of NFSV3SATTRTIME_TOCLIENT. This makes the server ignore the time values. My test program now creates poth testfile1 and testfile2. I might be wrong but I think the bug is in the client code and surfaced because Solaris 7 has become stricter about clients adhering to the protocol specs.
