I'd like to see the contents of /proc/slab_allocators through that... It gives the breakdown of allocated objects by allocators, so the fast-growing line in there will point to the leak. This bug was found by Tom, and I opened the report for him, so I'll do mybest to answer questions regard it. well, while I am running the test, I tried to look for the /proc/slaballocators. There is no such file on there, the only slabfile there is the /proc/slabinfo which doesn't change as the tests are being run. Is there somewhere else I can look at to find such information? IBM, The file you should be seeing is actually /proc/slab_allocators, with a "_" underscore. Thanks Jeremy West This event sent from IssueTracker by jwest issue 115885 I'm attaching the slab_allocators output from a test that I'm running. At this point in my test I'm seeing the amount of free memory continually decrease as the script continues to run. I'll update this BZ with a slab_allocators output closer to the end of the test. Thanks Jeremy West This event sent from IssueTracker by jwest issue 115885 it_file 85392 Two big allocators size-64: 322317 audit_log_task_context+0x46/0xad avtab_node: 165759 avtab_insert_node+0x28/0x89 Something tells me it isn't in the AVC or we would have found it long ago. Since Al's recent patch to audit_log_task_context does away with this allocation completely lets test on .68 and find out what we get. This appears to be a kernel memory leak fixed by a patch submitted by Al today. Transferring bug report to kernel team. Comment #6 is refering to BZ 228409 May mark as dup with testing results Is there a kernel update that we should try and verify this bug on? Sorry, should be fixed in .68 Thanks, I stress tested with the .68 kernel and it seems to be working fine. This bug can be closed. closing as a dup of 228409 since that patch also fixed this problem *** This bug has been marked as a duplicate of 228409 *** |
