I run the SNMP daemon and graph memory usage with Cricket (Cacti is probably the more popular way these days). My RHEL 6 server doesn't crash from this. I run a network backup system that does a full backup Friday nights and incrementals Monday-Thursday nights. Not much changes on this server, so the incremental takes only takes about 2 minutes (and doesn't do much other than read the directories). The full backup only takes about 7 minutes, but does read all files on the disk (a little over 2G). This is enough that the dentry cache frees a lot of its memory and the system keeps going. I'm not sure that's going to be sufficient in the long term though; the saw-tooth pattern on my graph is still creeping upwards (the drop in RAM usage each week doesn't go as low as the week before). -- Chris Adams <[email protected]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. _______________________________________________ rhelv6-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv6-list
