The 3100 is running Ultrix 3.0 and the RT is running AOS 4.3, Sep '88. Many, but not all, 3100 programs residing on the RT cannot be exec'ed--they ultimately fail with a swap error (probably can't page them in) as the RT server spews out the following (repeated many times): Aug 16 20:42:01 ursa-major vmunix: xdr_bytes: bad size FAILED Aug 16 20:42:01 ursa-major vmunix: svckudp_send: xdr_replymsg failed Now, I could start digging myself, but I wondered if anyone else has encountered this. Project Athena uses RTs as NFS servers and they behave flawlessly--their AOS code is not exactly the AOS 4.3 Sep 88 release, but the IBM NFS code hasn't changed much, I think. So, I'm a bit inclined to think the problem is with the 3100. Both machines are on the same thinwire ethernet, and there are no noticable problems with input or output errors or collisions. Before I get up to my elbows, has anyone else encountered this? -- Steve Dyer dyer@ursa-major.spdcc.com aka {ima,harvard,rayssd,linus,m2c}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu We have seen this a number of times here also. It has to do with NFS V4 not being entirely compatible with NFS V3 (which is what is in AOS 4.3). The best bet is to get IBM to release, productize, or whatever they call it, the latest version of NFS under AOS 4.3. Of course this might be considered development and we have been told that AOS is no longer being developed. -- Dan Ehrlich | Disclaimer: The opinions expressed are The Pennsylvania State University | my own, and should not be attributed Department of Computer Science | to anyone else, living or dead.
