Previous Comments: ------------------------------------------------------------------------ [2020-05-02 23:06:49] imnieves at gmail dot com Description: ------------ Several users of phpredis (a PHP interface to Redis) have noticed (in php from 7.4.0 and onwards) that TLS connections to Redis time out. When we establish non-TLS connections to Redis (using the same phpredis), we experience no timeout. I have personally verified the issue exists on all versions of 7.4 from 7.4.0 to 7.4.5, and that the issue does not exists on version 7.3.17 Test script: --------------- The test script is longer than 20 lines, so here is a link: https://github.com/phpredis/phpredis/issues/1726 Here you can find the script, its output, log trace, and explanation of test setup. Expected result: ---------------- The expectation is that TLS connections are either established or not in a consistent amount of time, but not seemingly randomly timing out (taking a large amount of time to fail). Actual result: -------------- The actual result is that TLS connections are being established in an inconsistent amount of time. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79559&edit=1
