Hello list, I am experiencing a memory leak with SuSE SLES9 x86_64 kernel 2.6.5-7.193-smp and a self-compiled DRBD 0.7.11. Slabtop shows "size-256" growing at a rate of about 50MB an hour: 4200585 4200585 100% 0.25K 280039 15 1120156K size-256 After a few days of this, the server runs out of RAM and requires a reboot. The problem only occurs on whichever node is currently primary and continues to occur regardless of the state of the primary. I have not been able to determine what is filling "size-256" and I think that would require a new kernel with some expiremental slab debugging patches. I searched the DRBD lists for memory leaks and all I discovered was the "bio" problem which appears to have been solved in version 0.7.10. I would also expect slabtop to show one of the bio pools as consuming the RAM instead of "size-256" if I was experiencing the bio leak. I am also not certain that DRBD is causing the leak but this problem does not occur on similar hardware / software configurations that do not use DRBD. Has anyone experienced anything similar? Is it possible to rule out DRBD as the cause of the memory leak? Thanks much, --Blake Atkins
