If we were on the same OS = version, we could then compare system specs a bit deeper, and see what = is different. Perhaps under 10.0 your symptoms would be closer to mine, = which may not be progress, but would be something.=20 I=92m afraid, we can=92t. We can only reproduce this on production = systems. And they cannot be easily upgraded right now. For one, we don=92t= have our build infrastructure ready for 10.x, because we usually skip = the X.0 release, which means no poudriere/pkg repo with locally patched = packages I need for these systems go into production. Then there=92s = testing, configuration changes needed, etc. It will probably be a year = until we can consider upgrading anything productive to FreeBSD 10.x. I could setup a test system on identical spare hardware, but as we = cannot trigger the problem without production load so far, there=92s no = point. Markus
