Hi, ATS 7.1.2, CentOS 7.4.
We have regular requests via ATS in reverse mode to get response time statistics and decide whether source is available. This request is excluded from caching, so it always results in TCP_MISS/200 in normal conditions with response time fluctuation depending on the distance of ATS server from source. Sometimes there are network errors that get logged as ERR_CONNECT_FAIL/502, after which there are again TCP_MISS/200 but with very high latency! This happens on all ATS servers we have deployed. For example, when normally before network error response times fluctuate around 150ms, then after they fluctuate around 1300 ms. After restarting ATS, response times are back to normal. Response times from log: 168 12979 2755 117256 56442 40104 1043 30955 30972 18418 26542 4172 8587 59259 4674 37166 16123 67019 41723 3497 6957 18684 17663 14634 20036 1305 14815 3526 10542 62519 22025 40556 36821 2342 2644 3695 7059 45581 1706 30947 16001 136383 1345 72770 1087 1311 1074 1080 1101 1033 1045 1057 1109 1078 1104 1059 1066 1062 1143 1074 1095 1207 1059 1067 1101 1110 1069 1394 1278 1323 1319 1315 1317 1317 1343 1270 1284 1362 1446 1363 1302 1321 1330 1317 1335 1346 1312 and after restart: 593 362 129 381 361 380 394 394 117 384 341 112 88 363 397 93 385 356 371 360 411 120 338 497 449 377 131 458 161 372 112 364 87 129 340 93 114 338 377 454 424 381 381 348 129 336 116 404 108 340 114 Best regards, Veiko
