Yesterday we added 256mb to a batch of servers, doubling them to 512k. One of the batch was running an older kernel/world than the others. The older one was circa Dec97 (cvsup'ed 2.2 stable) and the others were circa Feb 98. We removed "options BOUNCE_BUFFERS" from the kernel after reading about problem with >256mb. Installing the same kernel on all machines, they all rebooted fine, however the most out of date server showed no sign on any 'Cache' being used under 'top', instead it showed tons of 'Free' memory. The other machines filled their caches up just fine (which was our primary goal in adding more memory). Thinking the kernel (taken from one of the more recent servers) might not quite match with the rest of the world, we built a new kernel on the older box, same problem; next we tried a complete make world on cvsup'ed sources from yesterday (2.2.6-BETA) - same problem. Anyone seen this ? The /etc/rc* files look up to date. The machines are 300mhz PIIs. baffled, rob -- Rob Hartill Internet Movie Database (Ltd) http://www.moviedatabase.com/ .. a site for sore eyes.
