[Dnsmasq-discuss] dnsmasq consuming more memory

[shashikumar Shashi]

Hi Simon Kelley,

dnsmasq is running continuously for around five months, we had around 150
clients. After 5 months dnsmasq got killed by the kernel, due to cgroup
memory limit.
It utilizes around 2GB of memory.
Are there any known issues, we are using 2.80 dnsmasq version?

kernel: [ pid ]   uid  tgid total_vm      rss nr_ptes nr_pmds swapents
