Hi, we are currently stress-testing two 5.1 machines. Each of the machines have a 2.6GHz P4 and 512 MB RAM. The machines are running zebra, ospfd and nscd. We bomb the machines with many DNS requests (up to 50k/s), transmitted over Gigabit Ethernet. Unfortunately, both machines panic soon after starting the tests, and both go down with "kmem_malloc(4096): kmem_map too small" and says the current process is "4 (g_down)". I'd love to present a coredump and a backtrace, but somehow it just doesn't dump, it rather panics again with "ata_dmasetup: transfer active". Well, if I get this right, it means that the kernel VM is exhausted. Is there anything I can do apart from using more RAM? regards, le --=20 Lukas Ertl eMail: l.ertl@univie.ac.at UNIX-Systemadministrator Tel.: (+43 1) 4277-14073 Zentraler Informatikdienst (ZID) Fax.: (+43 1) 4277-9140 der Universit=E4t Wien http://mailbox.univie.ac.at/~le/
