I reboot weekly. No I don't get the errors when I remove the environment variables but I get tremendous packet loss. -----Original Message----- From: Martin Holste [mailto:mcholste () gmail com] Sent: Monday, July 18, 2011 3:21 PM To: Gibson, Nathan J.

(HSC) Cc: snort-users () lists sourceforge net Subject: Re: [Snort-users] Question That error message indicates the box doesn't have enough RAM for PF_RING to allocate its memory. Are you sure you're not low in RAM for the box? That might also be a product of using PCAP_MEMORY=6120. Try removing the environment variables as they shouldn't be needed anyway when using PF_RING (as the modprobe.conf settings control it). On Mon, Jul 18, 2011 at 9:42 AM, Gibson, Nathan J.

I have been running the same rule categories for a year. All of the sudden (about a month ago) snort started randomly stopping with no apparent errors in the logs. The only error I get is when I try to restart snort I get the following error. 7/18/2011 9:33 AM : snort[7491]: FATAL ERROR: Can't start DAQ (-1) - can't mmap rx ring: Cannot allocate memory! As I said the only variable I have are the actual rules that are updated from ET and Sourcefire. Could a rule be causing this?
