    • RE: DNS queries during backup job

      Although it is nice that there is work arounds for the DNS spikes with either nscd or the in-process DNS cache, i think the DNS spikes are a symptom of a whole different issue.

      I think we can safely assume that each DNS lookup is corresponding to one attempt at establishing a TCP connection then there is some code somewhere that spawns an awfull lot of short lived connections instead of reusing / pooling them - with all the issues that follows in that area (insufficient ulimit NOFILE, connections in TIME_WAIT/exhausting of client ports etc)

      In the first picture of "hostname and dns configuration":
      It doesn't look like you have any double colon '::' in the first 2 entries but you have them in all fields on the last picture

    • RE: XO Sources - yarn build - javascript heap out of memory

      You do need a lot of virtual memory for build but you can get by with 2GB ram + 4 GB swap if you tell nodejs to limit it self, by setting

       export NODE_OPTIONS='--max-old-space-size=3072'            
      

      before starting the build process
