- We began experiencing these errors. We do not know exactly when
- it started. But it could have been because of Ultrix 4.2a.
- On a 5000/240 the errors were infrequent. On a 5000/200 they
- occurred twice an hour on average. It seemed tied the the # of
- seconds on the clock. IE: the occurance pattern was like:
- 4:28:43
- 4:58:43
- 5:28:43
- 5:43:43
- 6:28:43
- ...
-
- The seconds # changed every time we rebooted it.
-
- Digital replaced the system board on both.
-
- I just checked. The 240 is OK now, the 200 just spat out 2 errors
- today after being up for 2 days. They had the same # of seconds.
-
- We have another 200 with no problem.
- We have other 240s with no problem.
- So, you tell me?
