Memory leak with html output?
I installed the dns looking glass on my server, I almost exclusively use the OpenMetrics output format but the service was being picked up by my healthcheck service (around 8 requests per minutes) which by default request
/ using the default html output.
After a few days I noticed a steady increase of memory usage coming from the dns-lg. After restarting the service and excluding it from the healthcheck the memory usage was back to stable. This lead me to wonder if the html formatter is not leaking memory.
