On this double Xeon, yes. I had no problems before with 2.6.12 and the same "heavy" software on dual Opteron and dual dual core Opteron machines, and this is my first installation on a EM64T. At first it seemed everything was ok with 2.6.12 here too, but in a couple of days we started gettings some of those oom killings when running some Gaussian jobs. In at least a pair of cases the system froze completely. > If you're feeling keen you could add this patch which would confirm it: Added it and already got output for a similar "killing". Since I'm not sure what could be most relevant among those messages, I refrained from attaching them all here, and instead put them at http://jmce.artenumerica.org/tmp/linux-2.6.12-oom_killings/EM64T-kern.log > And if it's that bug then I'm afraid you'll have to sit tight until 2.6.16. > We shouldn't release 2.6.16 until this thing is fixed. Do those call traces suggest that uncorrected bug you mention? (And if yes, is there any known way to mitigate the problem? Could it depend on BIOS settings?) I'll also be able to try a 2.6.15 kernel (eventually with any suggested patches) later today... Thanks again and best regards J Esteves -- +351 939838775 Skype:jmcerqueira http://del.icio.us/jmce
