Gents,<br> Thanks all for the suggestions. Specific responses below<br> <br>Rmkml - I made your recommended change to the suricata.yaml file (- profile: low) and there was no change. Watching top the spike appeard to peak at 3.7GB then Suricata exited.<br>
<br>Dave - I have to admit that I'm not versed in C so I can't build the program you're describing. Do you know where I could find a pre-built one? I agree that upgrading to a 64-bit version would be the best choice, however I'm up against a very short timeline here and won't have time to upgrade the OS the reinstall Suricata and the rest of the tools that I need. <br>

<br>I'm not exactly sure what I'm looking at here, but it looks like my max memory size is unlimited. Am I reading this correctly?<br>I've also looked over your screen capture from your Ubuntu 32-bit VM and can't figure out why I'm crashing. What version of Suricata are you running on that 32-bit Ubuntu VM? 1.1b2?<br>

1.1b2 build from the tarball. Not using git. The machine
is running the 32 bit version of CentOS5.6, but we just
applied the kernel-PAE packages today to allow it to utilize
more than 4GB of ram. Is this what you are talking about,
Dave? Lastly I included the suricata.yaml file as well as
the output from free -m and my collectl memory statistics
during the fatal run.<br>
<br>
Thanks for helping out with this. I thought that bumping
the ram up to 16GB would fix it, but it appears not. Maybe
I'll start slicing off some rules and see where the
threshold lies...<br>
