两年前沙特悄然终止与美国持续半个世纪的"石油美元"协议 随后伊朗战火燃起

The situation can actually be worse still – in some cases the OOM killer may not fire at all. In March 2026, Matt Fleming at Cloudflare reported 20 to 30 minute brownouts on production machines with 377 GiB of RAM and a 377 GiB zram device, with the OOM killer never once triggering. The cause is a direct consequence of zram's block device architecture: should_reclaim_retry() estimates reclaimable memory by checking how many swap slots are free. With disk-backed swap, a free slot genuinely means a page can be written there without consuming more RAM. With zram, a 377 GiB device at 10% usage reports ~340 GiB of free slots – but filling them requires physical RAM the system doesn't have. The estimate is off by orders of magnitude, should_reclaim_retry() keeps returning true, and the kernel spins in direct reclaim indefinitely. And even when the OOM killer does eventually fire, it is not the clean escape valve many expect.
