Saario >Organization: >Release: FreeBSD 2.1-STABLE i386 >Environment: Kingston Ethernet Card.... FreeBSD 2.1 on a P133 with 64MB of memory 77MB swap space. Adaptec SCSI controler with Conner 1.0GB drive. High volume web server running Apache! >Description: I bought a Kingston card with the DEC DC21040 chipset since it said this chipset was supported. I used the de0 driver and it worked fine. At first I forgot to turn off PlugNPlay and the network stopped working after 6 hours with a mb_map full messsge to the console. Then I noticed there seemed to be about twice as much Active memory used as with the 3C503 card I used before and also the Cache memory as displayed by top was 20M.... I rebooted and everything worked. Later I disabled plug and play, it didnt' crash but is still using up all that memory and slowly grabbing more. It didn't seem to do much at first but after an hour of heavy use it seemed to shoot up in a few minutes when I was not watching top. Then it stabilzed for awhile. >How-To-Repeat: Running a high volume web server with a Web Chat page....many hits a second. >Fix: I don't know but I may try a SMC card?
