Well, to be fair you can't really know that without actually understanding what his applications are doing. It could be they allocate a lot of memory but most of that memory is usually inactive, which would be a reasonable use for swap. There's a good chance your advice is correct but I'm just saying not necessarily. -- Taroon-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/taroon-list
