I'm not a coder; but I found source for viomb; which calls uvm_pglistalloc; which calls uvm_pmr_getpages which mentions ENOMEM: https://cvsweb.openbsd.org/cgi-bin/cvsweb/~checkout~/src/sys/uvm/uvm_pmemrange.c?rev=1.66&content-type=text/plain There I found this comment: * fail if any of these conditions is true: * [1] there really are no free pages, or * [2] only kernel "reserved" pages remain and * the UVM_PLA_USERESERVE flag wasn't used. * [3] only pagedaemon "reserved" pages remain and * the requestor isn't the pagedaemon nor the syncer.
Unsure how I might use this information to get rid of the previously mentioned error message.. On Tue, May 14, 2024 at 2:28 PM Peter J.
