Hi there We have a snort box that has daemonlogger running on it as well as snort. It was crashing via 27982 setsockopt(3, SOL_SOCKET, SO_ATTACH_FILTER, "\3\r\202H\377\177\0\0000tp\0\0\0\0\0", 16) = -1 ENOMEM (Cannot allocate memory) 27982 setsockopt(3, SOL_SOCKET, SO_DETACH_FILTER, [0], 4) = 0 27982 write(2, "Warning: Kernel filter failed: C"..., 54) = 54 This is a CentOS-6 64bit system with 4G RAM. I know that's not much, but there's no swapping. There is a BPF filter - but I tried it with no filter and it crashed too We also have other identical boxes that don't show this symptom. I just know that if I reboot this problem will be magically "solved" - but that is obviously not a real solution Can someone explain to me just what is behind this issue, as I need to be able to figure out just which of our boxes are "underspec'ed" Thanks -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
