Will try. I've found one more clue. I've added various graphs to my monitoring. Also I've been segregating various traffic kinds into different haproxy backends. Yesterday test shows this: https://pasteboard.co/HpPK2Ml6.png This backend (sns) is used exclusively for static files that are "large" (from 10KB up to over a megabyte) compared to my usual traffic (various API calls mostly). Those 5xx errors are not from the backend servers, "show stat": sns,kr-8,0,0,5,108,,186655,191829829,19744924356,,0,,0,0,0,0,UP,100,1,0,0,0,15377,0,,1,4,1,,186655,,2,7,,147,L7OK,200,1,0,184295,550,0,0,0,,,,,8895,0,,,,,0,OK,,0,12,4,1474826,,,,Layer7 check passed,,2,5,6,,,,10.7.1.8:81,,http,,,,,,,, sns,kr-10,0,0,2,105,,186654,191649821,19977086644,,0,,0,0,0,0,UP,100,1,0,0,0,15377,0,,1,4,2,,186654,,2,7,,148,L7OK,200,0,0,184275,551,0,0,0,,,,,8823,0,,,,,0,OK,,0,21,4,1473385,,,,Layer7 check passed,,2,5,6,,,,10.7.1.10:81,,http,,,,,,,, sns,BACKEND,0,0,8,213,6554,383553,391967657,39722011000,0,0,,0,0,0,0,UP,200,2,0,,0,15377,0,,1,4,0,,373309,,1,14,,332,,,,0,368563,1101,0,1873,12008,,,,383545,27962,0,0,0,0,0,0,,,0,18,5,1763433,,,,,,,,,,,,,,http,roundrobin,,,,,,, -- Janusz Dziemidowicz
