hi to all, the same effect I got after I upgraded the snort versions from 2.8.6.1 to 2.9.1.2. I also tried to find the reason for it and I'm still looking. I've run also the two versions parralell on one the machine which runs nothing else than snort ids. I've analysed the outputs and couldn't find something, that can point to the reason. Still the snort process of the new version shows using far more than doppell usage than the snort process of the old version (both in cpu and mamaory). I've installed the both version on FreeBSD 8.0 machine. If someone had the same bad experience and can give us an idea, how it can be solved, I would be more than grateful. regards yoas 2011/12/17 babu dheen <babudheen () yahoo co in>
Dear All, In recent past, we are experiencing high CPU usage on one of Astaro firewall where Snort -IPS functionality is enabled. Snort almost consumes 90% of the CPU. During such time, we could see only one snort instance used to run and could not find name of the signature which causing high CPU usage and because of this high cpu usage all TCP connection keep getting dropped. To solve this problem, we had to reboot the Astaro firewall device. Would like to know why snort uses high CPU or in which situation snort can consume more CPU usage. Is there any way to find out which signature consumes more CPU in snort during high CPU usage time?****** Regards **Babu ** ------------------------------------------------------------------------------ Learn Windows Azure Live!
