Amen, brother. Words of wisdom. I've been bearing in mind the possibility of outcomes like that during acceptance testing, and thus would then adopt a fallback of adding a swap file. Swap files were common in Linux systems of the early '90s, but then fell out of use because swap partitions has a perfomance advantage. But then, someone found and fixed the performnce gap in the 2000s. Most admins just don't remember the option exists. _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
