It's running latest 5.4-RELEASE, swap is on a SCSI disk, single processor. IIRC GEOM should handle ENOMEMs by retrying the IO, but I'm asking just in case - are these errors something I should worry about? -- Every sufficiently advanced magic is indistinguishable from technology - Arthur C Anticlarke
