Hi, I have a problem - from time to time my ATS 7.2.1 has problems with serving static files from origin, client transactions last over 10s and I see the following diagnostic (I have enabled logging "slow requests")
cache_open_read_begin: 0.000 cache_open_read_end: 10.640 Any requests to the same URL are blocked for over 10s. Restarting ATS solves the problem. What does it mean? Does it have to do with open_read feature? but the timeouts don't add... Any suggestions appreciated! Here's my records.config with configs related to avoiding thundering herd... CONFIG proxy.config.cache.enable_read_while_writer INT 1 CONFIG proxy.config.http.background_fill_active_timeout INT 0 CONFIG proxy.config.http.background_fill_completed_threshold FLOAT 0.000000 CONFIG proxy.config.cache.read_while_writer.max_retries INT 5 CONFIG proxy.config.cache.read_while_writer_retry.delay INT 200 CONFIG proxy.config.http.cache.max_open_read_retries INT 5 CONFIG proxy.config.http.cache.open_read_retry_time INT 200 CONFIG proxy.config.http.cache.open_write_fail_action INT 2
