I'm running some heavy tests on my machine (256Mb RAM, HDD, no swap, 4.11-RELEASE) such as "make buildwolrd". After successful completion of this procedure I issued "rm -rf /usr/obj/usr" and got the following (single) message from kernel: Mar 3 11:05:32 test3 /kernel: swap_pager_getswapspace: failed Does anybody know whether it's harmless?
