https://bugzilla.suse.com/show_bug.cgi?id=1183843 https://bugzilla.suse.com/show_bug.cgi?id=1183843#c2 --- Comment #2 from Martin Wilck --- I observe that the kernel crashes with OOM, the kmalloc-192 cache is ridiculously large:

The client must still limit max_sectors_kb e.g. by an udev rule, so that the target's limits aren't exceeded.
