(480 stones/sec?) running vmstat on the system gives the following results, with one user on the system... # vmstat 2 procs memory page disk faults cpu r b w avm fre re at pi po fr de sr r0 x1 x2 x3 in sy cs us sy id 1 0 0 445 7769 0 0 0 0 0 0 0 3 0 0 04994 18 4 1 82 17 1 0 0 445 7769 0 0 0 0 0 0 0 0 0 0 05156 163 5 0 83 17 1 0 0 445 7769 0 0 0 0 0 0 0 0 0 0 05170 107 3 0 83 17 0 0 0 423 7746 0 0 0 0 0 0 0 0 0 0 05178 73 1 0 81 19 0 0 0 423 7746 0 0 0 0 0 0 0 0 0 0 05183 49 0 0 84 16 0 0 0 476 7742 0 0 0 0 0 0 0 2 0 0 05179 35 0 0 81 18 0 0 0 476 7742 0 0 0 0 0 0 0 0 0 0 05182 26 0 1 78 21 0 0 0 476 7742 0 0 0 0 0 0 0 0 0 0 05187 20 0 1 84 15 0 0 0 157 7742 0 0 0 0 0 0 0 0 0 0 05190 16 0 1 82 17 0 0 0 157 7742 0 0 0 0 0 0 0 0 0 0 05192 13 0 0 84 16 0 0 0 375 7742 0 0 0 0 0 0 0 0 0 0 05201 8 0 0 82 18 the interupts per second are averaging more the 5000 on an 'idle' system. our loaded up vax 750 running 4.2 gives the following results from vmstat... # vmstat 2 procs memory page disk faults cpu r b w avm fre re at pi po fr de sr h0 r0 u0 f0 in sy cs us sy id 2 0 0 1139 3207 0 1 0 0 0 0 0 3 0 1 0 4 68 20 18 25 57 1 0 0 911 3185 0 0 0 0 0 0 0 0 0 0 0 3 239 18 6 19 74 1 0 0 911 3185 0 0 0 0 0 0 0 0 0 0 0 2 180 14 3 14 83 1 1 0 868 3176 0 0 0 0 0 0 0 20 1 0 0 10 133 13 5 22 73 1 1 0 868 3176 0 0 0 0 0 0 0 0 0 0 0 6 111 10 4 13 83 0 0 0 629 3173 0 0 0 0 0 0 0 0 0 0 0 4 96 8 4 19 77 0 0 0 629 3173 0 0 0 0 0 0 0 0 0 0 0 2 88 8 3 15 82 0 0 0 629 3173 0 0 0 0 0 0 0 0 0 0 0 2 88 9 6 16 77 all of the ports had been shut off on the 785, thinking that a runaway getty may have been the culprit, but no change was evident. another thought was the DEC ethernet board may be the bad guy. anyone got any clues/ideas? the 785 must be fast, as the response time was fairly fast even with the 5000+ interupts/second running rampant. any/all ideas would be appreciated. please respond directly to me at: ihnp4!dicomed!salmi john salmi dicomed corporation minneapolis, mn 612/885-3000 and, as always, thanks in advance :-)
