I've done this for the instances on our development machine. Unfortunately, the instances on the production machine are not "owned" by us so I need to keep them as stable as possible. > I cannot work on this right now as I'm really busy, I'll try to > do that after > Wednesday, when I do my last exam for this session.

I'm uncertain of exactly why this would be different. However, I suspect that active use is a factor. The first instance to crash was our heaviest customer (approximately 14 hours post-upgrade). The third instance was our second busiest customer (approximately 20 hours post-upgrade) while the second to crash was a barely used instance (approximately 19 hours post-upgrade). > Do they behave differently so that they trigger the introduced bug? > I.e., do you know of any particular behaviour of programs in the hanging > instances? Unfortunately I don't have access to most of the production instances. While I host them, I have to tread carefully. As a result, I only have general ideas about what is happening internally. However, we will see if I can reproduce the problems with 2.6.15.3-bs1 on our development instances.
