Hi Guys,<div class=""><br class=""></div><div class="">I have a squid-3.5.28 installation that is deployed to do transparent ssl-bump of HTTPS traffic (linux bridge, tproxy). The server is not overly busy, CPU and RAM usage is low + no swap being used yet regularly the squid service is choking HTTPS traffic to a point where websites are timing out. Any other traffic flowing through the bridge is unaffected and continues to operate at normal expected speeds.</div><div class=""><br class=""></div><div class="">I have checked all obvious things, CPU/RAM usage, network interface errors, conntrack table and TCP resource exhaustion yet all look fine. There is no caching taking place and disk IO is not a problem.</div><div class=""><br class=""></div><div class="">During the times where squid is slow, even using squidclient to query squid state is extremely slow to respond, as you can see below snip from the access.log the mgr:coutners and mgr:5min requests are taking up to 30 seconds to complete when usually the response time is 0:</div><div class=""><br class=""></div><div class=""><font face="Courier New" class="">1551397216.978 31 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397220.633 0 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397233.385 2 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397237.431 14 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397262.074 2 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397280.644 17 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397314.764 1 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397330.455 5 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397377.265 4 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397385.727 0 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397396.161 17 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/5min - HIER_NONE/- - -<br class="">1551397432.974 11 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397462.897 11 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397492.759 7 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397522.611 9 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397552.521 12 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397582.484 17 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -<br class="">1551397612.446 10 127.0.0.1 TCP_MISS/000 0 GET cache_object://localhost/counters - HIER_NONE/- - -</font></div><div class=""><br class=""></div><div class="">I have a number of these severs deployed, all running same hardware/config/squid versions and only this one is experiencing an issue.....looking for suggestions on what could be occurring and how to debug further? </div><div class=""><br class=""></div><div class="">Thanks,</div><div class=""><br class=""></div><div class="">Michael</div></blockquote></div><br>-- <br>Diese Nachricht wurde von meinem Android-Gerät mit K-9 Mail gesendet.</body></html>
