IOT trap (core dumped) adb said SIGIOT 6: undefined The problem was eventually traced (by Sun UK support) to this erroneous line in /etc/fstab grumpy: /ufs/digest /ufs/digest nfs ro 0 0 Experienced administrators (unlike me) will be able to see the problem immediately: it should be grumpy:/ufs/digest /ufs/digest nfs ro 0 0 Isn't it amazing what an extra space can do? The moral of this tale is, if your dump starts to misbehave, check /etc/fstab *very* carefully. I'm still running 3.2 on a 3/160, but the 3.5 binary does exactly the same thing. I don't know about other versions of SunOS or different processors. Don Ward Systems Design Division GEC Electrical Projects Ltd Email: Don_Ward@gec-epl.co.uk Boughton Road, Rugby, CV21 1BU UK.
