I agree I had freeze problems on machines, usually at night, with almost nothing in the logs. I had a clue with ide errors, timeouts, and so on, but... 2 machines were connected to a enterprise-wide lan, and for replication shared a private gigabit switch on a second NIC. this switch was DC powered and had no electrical grounding. Once I had wired this switch to both chassis (the switch and the 2 machines were close to each other), my problem disappeared and since that no one did freeze anymore. I think that the sustained load of 200+ Mb/sec due to rsync'ing file systems at night was generating some static charges and that sometimes there were discharges generating at least io errors or at most system freezes. I think electrical weakness is really a clue to most freeze problems hth A 19:48 17/11/2004 +1100, vous avez écrit : >Rushan, > >Machine freezes are a hard one to solve, but in the main, I've found >they're caused by hardware failures or conflicts. > >Have you added any new hardware to the machine not long before the >problem has started occuring? > >If you have, then that might be the cause.
