[etc] I think this is an issue: - As stated, machines running 4.x don't seem to do it - In addition to the mode schizophrenia, undex 5.3 I'm also seeing resets of several seconds which don't happen on identical hardware running 4.11 in the same rack. Yes I know the clock drifts will be different, but ntp.drift is very close on the two boxen. I believe something's broken. More datapoints: - I'm seeing it under 5.3R both on i386 and amd64 but not i386/4.11 on the same LAN - I'm not seeing it on 5.1R on a remote system -- Bob Bishop +44 (0)118 940 1243 rb@gid.co.uk fax +44 (0)118 940 1295
