If not, it is not caused by what these patches were intended for. (They are in 10.3.) Your crash basically indicates that either: 1 - The sg_group was free'd when a socket upcall was still in progress. Since the sg_group structures aren't free'd until the nfsd threads are killed (shutdown or ??), I don't think this can happen during normal operation. OR 2 - The xprt structure that referenced the sg_group was free'd prematurely and the sg pointer was bogus. If it was #2, I think I can come up with a simple patch to avoid this. (Basically acquire a reference count on the xprt structure during the socket upcall.) rick --=20 You are receiving this mail because: You are on the CC list for the bug.=
