The quota groups are on and the symptoms match the known problem when there are lots of backrefs. krealloc is on the stack although not mentioned explicitly, called through ulist_add_merge. The allocation order is 6 from the OOM report, means that somebody wanted a large congiguous chunk of memory, which is what the krealloc did and failed. Kernel memory is fragmented and this kind of allocations is hard to satisfy in the long run. david -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
