The reason of checking 5-STABLE, is that I have encounter problems w DL380 and 6-STABLE (mine are all G3's). But I could not get any real info out of it and could not proceed to make a report. Mine just rebooted (power cycled), like if someone pulled the powercables and put them in again. So nothing in the log, and no dump in /var/crash (Yes, I specified it.). The ilo only reports a power cycle. What I do know is that it happens more often with high IO load. Network of 200-300Mbps in and out, a lot of memory and disk activity. One other thing I noticed was that they mostly occured at 00, 15, 30 or 45. (according to logs and ilo) But I could not see anything in cron, logrotate or anything that could cause it to boot at those times. I disabled the checks for server overload in the bios settings and still the power cycled. But it couldnt have been a problem with the hardware, since with 5-STABLE it can run for months without problems and with 6-STABLE it can crash anywhere from 2 hours to a week. Sometimes it can crash several times in one day and then be stable and fine for a week. If you get a solid 5-STABLE and the 6-STABLE is still a problem, it will be one more than me (that I know of) that have encounter problems. As my boxes are in production, I cannot switch to 6-STABLE just to test things. So if you are able to do all the steps that needs to be done and post a problem report, it would be great, from my point of view. And then I can only hope that it is the same issue. /Bjorn
