I have upgraded www, www2, and eskinews to Linux 2.2.14 today. I have increased the MaxClients on www2 to 80, with the old kernel this would usually cause it to crash and burn in a few minutes owing to some weirdness in the memory paging. The 2.2.14 kernel seems to have fixed some problems with system memory management, particularly, no longer does the kernel attempt to allocate huge amounts of memory to buffers that aren't actually in use. It also seems to return memory that is no longer in use now, instead of seeing it just go up and up until it dies in swap hell, it varies as programs consume more and less. I am leaving the MaxClients set to 80 on www2 to see if this problem is really cured, it helps performance considerably for it to be that high (it has been at 50). If any of these machines die, please get any messages on the console, whether they are spinlock(), or OOPS, or some other error. I would be curious to hear from people with virtual domains with respect to any perceived changes in performance.
