cpu usage suddenly high - not sure why

[sphen13]

just happened to notice on my esxi cpu graphs that its been higher than normal. the server i have running the latest version of stalwart seems to be running ~ 80% cpu - but also i see high resource usage on systemd-resolve. turning logging up to debug doesnt show much more of anything in the logs. i presume it is doing something with dns which it never did before but curious how i can better see what it is doing.

dns is working fine on the server and no other changes have been made other than updating stalwart. hmm.... thoughts?

This is a bug with the resolver library that Stalwart uses. Please upgrade systemd-resolved or disable DANE.
