Description of problem:when using RH 8.0, periodic checks with free shows that cached memory increases and is never released. Opening or running various progams causes the cahced memory to expand; but it is never released. While in init runlevel 3, i initialized my tripwire database; cached memory grew to within 90% of my installed RAM (1.79 gigs of 2gigs) I noticed a problem using sybase, Studio 3.3, and just logging onto the system Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1.open and run varius prorams ie..initalize tripwire 2.make periodic checks of system with free 3. Actual results: You will see that cached ram increases and doesn't seem to be released. Expected results: Additional info: I think there is something wrng witht he overall system..that is why I included kernel as a component
The system caches anything it can until the memory is needed for another purpose. So that isnt a bug. Older RH kernels such as the one shipped with 8.0 were a bit bad about giving it back sometimes and could underperform. Errata kernels should have resolved this If not please re-open giving the errata kernel you are using
I'm afraid this behaviour has not been fixed at all (at least with my work loads). With squid running and doing constant disk reads and writes both cache and buffer increase to the point where the kernel starts swapping large parts of squid out over time. This bug seems to be a duplicate of #89226.
Please can you give the kernel errata you are currently running
2.4.20-18.9smp on Red Hat 9, fully patched (to the best of my knowledge)
I'm going to backport the latest -rmap upgrades to this kernel
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
