phpRedisAdmin causes an error in some cases

When i try to show some keys it's causes an php timeout error. key value via redis-cli:

__flash|a:1:{s:5:"error";i:-1;}_lang|s:2:"ru";error|s:72:"\xd0\x94\xd0\xbe\xd0\xbb\xd0\xb6\xd0\xb5\xd0\xbd \xd0\xb1\xd1\x8b\xd1\x82\xd1\x8c \xd0\xb2\xd1\x8b\xd0\xb1\xd1\x80\xd0\xb0\xd0\xbd \xd1\x85\xd0\xbe\xd1\x82\xd1\x8f \xd0\xb1\xd1\x8b \xd0\xbe\xd0\xb4\xd0\xb8\xd0\xbd \xd0\xbc\xd0\xb0\xd1\x80\xd1\x88\xd1\x80\xd1\x83\xd1\x82";wizard-fields|a:11:{s:6:"format";s:6:"single";s:11:"description";s:5:"qweqw";s:8:"contacts";s:5:"qweqw";s:6:"single";O:20:"yii\\web\\UploadedFile":5:{s:4:"name";s:38:"da-ne-bred-kakoy-to_71842425_orig_.jpg";s:8:"tempName";s:76:"/workspace/sttk2/public/upload/20160714_cc1e5a1562f60d90abccdf3cd6492067.jpg";s:4:"type";s:10:"image/jpeg";s:4:"size";i:54584;s:5:"error";i:0;}s:6:"slider";a:0:{}s:5:"vidos";N;s:10:"rubricList";a:10:{i:0;s:1:"1";i:1;s:1:"2";i:2;s:1:"3";i:3;s:1:"4";i:4;s:1:"5";i:5;s:1:"6";i:6;s:1:"7";i:7;s:1:"8";i:8;s:1:"9";i:9;s:2:"10";}s:9:"routeList";a:0:{}s:14:"views_per_hour";i:1;s:11:"video_range";i:5;s:9:"user_type";N;}

browser wait for web server response until catching php timeout error current value contains php serialized string with some cyrillic symbols, may be it is what causing error

web server logs looks like that:

2016/07/13 12:53:50 [error] 2972#2972: *4916 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 127.0.0.1, server: _, request: "GET /view.php?s=9&d=9&key=session%3Ad95e9a2ef6b1c06a15f3bd2eb759ab42 HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "pra.local", referrer: "http://pra.local/?view&s=9&d=9&key=session%3Ad95e9a2ef6b1c06a15f3bd2eb759ab42"
