I'm getting this warning from fread: "Mapped file ok but madvise failed"
It seems to be purely a function of file (and, looking at the code, I assume memory page) size and is system dependent, so I can't really give you a reproducible example. Adding or removing a single character anywhere in the file results in the warning disappearing. Two questions - should I care about this warning? And can the code be changed to be aware of this edge case? -- View this message in context: http://r.789695.n4.nabble.com/fread-warning-tp4669997.html Sent from the datatable-help mailing list archive at Nabble.com. _______________________________________________ datatable-help mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/datatable-help
