Robert, can you see if the unexpected OOM kill results still a problem with the latest RHEL3 IA64 kernel? It is located in: http://people.redhat.com/~lwoodman/IA64/ Also, FYI, the pagecache memory that was mapped into a process which was OOM-killed will not get freed up immediately. Instead, the reference count will be decremented accordingly and the pages will remain in the pagecache until they are either reused by some other process or the system deems in necessary reclaim and free them. The system is not leaking memory, its just holding on to cached filesystem data pages. If that results in pre-mature OOM kills then thats a separate problem, not a memory leak. We have made several changes to the kernel since the 2.4.21-9.EL that will delay and/or eliminate OOM kills and that what I want you to test for us. Larry Woodman Larry Woodman At least 2.4.21-27.EL solves this issue for me - at RHEL3. RHEL4 doesn't have already this problem. Thank you, Larry :) An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
