Hi. I am using Turris Omnia since the beginning of this year and am generally very satisfied with it.
Recently (since the recent or first November patch), however the Router regularly stops accepting connections on ssh and throws a 500 on all frontends. Access to the logs is impossible in this case and only a reboot works.
During manual monitoring I have seen an increase in the memory usage of kresd. Overnight its memory consumption has increased from ~5% to ~53%. This fits with the observation, that the router needs to be restarted regularly.
A colleague of mine also uses this router and does not have this issue. We both have installed
knot-libs - 2.9.6-1
knot-libzscanner - 2.9.6-1
knot-resolver - 5.1.3-3
Could this be a memory leak in kresd? How can I diagnose it further?
