3.0.3 Segmentation fault (core dumped)

Hello, Running 3.0.3... from ppa:freeradius/stable-3.0 /usr/sbin/freeradius -v freeradius: FreeRADIUS Version 3.0.3, for host x86_64-pc-linux-gnu, built on May 20 2014 at 11:59:21 Am running four instances (in docker containers) on two VMs... behind a load balancer. After running for a couple hundred hours, instances start hitting seg faults... restarting the instances gets them going again for few hundred hours... How would you debug this in production settings? should I upgrade to newer version first? Thanks, Mohamed.
