Hi. need help here. Using RHEL 4 update 5 with 4 GB of memory. (kernel 2.6.xx) Have an application that is used by maybe 80 to 100 users at a time, but disk cache doesn't seem to give way to the application and at times, the system will swap in/out heavily, which blocks the running processes, even though there's still 2.5 to 3 G in the disk cache.
tried swappiness = 0 but no dice. is it possible that the apps is limiting it self to use a smaller memory? or is it possible that the disk cache does not shrink because the pages are always dirty? Long term and expensive solution is to add more memory, but before that, any insights will be helpful. -- --- Kelsey Hartigan Go Registered Linux user #5998
