[azerty32]

Ahojte, pouzivam nginx a na spracovavnie php php5-fpm z dotdeb. Po dlhom case sa mi zacala objavovat hlaska 502 gateway timeout a v error logu nachadzaom toto:

2012/09/05 11:37:19 [error] 3353#0: *419 upstream timed out (110: Connection timed out) while reading response header from upstream, client: _, server: www.example.com, request: "GET /example.php HTTP/1.0", upstream: "fastcgi://unix:/tmp/php.sock:", host: "example.com", referrer: "http://example.net/example.html"

Na otázku zatím nikdo bohužel neodpověděl.
