php - connection reset by peer in java -


scenario:-

client application - javascript based

front-end processing - php hosted on apache using xampp(php 5.3.8, xampp 1.7.7, apache 2.2.21)

back-end processing - java rest apis hosted on tomcat

description

browser send post data php server , php validate , modifies post data according it's need , open connection back-end server(tomcat server hosting jersey rest apis) using curl , tomcat server return response php in-return sent browser.

problem facing :-

tomcat server takes 3 10 min process request(depending on payload , type of request, higher payload more more execution time). when higher payload request or time-taking request (7-10 mins) api called socket exception occurs stating "connection reset peer" @ tomcat hosted rest apis (backend). nothing happens @ front-end processing php logic. connection reset java rest api cannot send response , there nothing happening on php cannot course-correct happening.

now, if same time-consuming or payload wise api call made through rest client (chrome extension) apis processes , return response rest client. zeroes down issue on php or apache front.

already tried: in httpd-default.conf -

keepalive on

timeout 2100

keepalivetimeout 2100

in php curl call - 

curl_setopt($ch, curlopt_timeout,0); curl_setopt($ch, curlopt_connecttimeout ,20); or  curl_setopt($ch, curlopt_connecttimeout ,20); curl_setopt($ch, curlopt_httpheader,                  array('content-type: application/json ',                     'content-length: '.$len,//length of content                     'connection: keep-alive',                     'keep-alive: 2100')); set_time_limit(0);

xdebug turned off default_socket_timeout = 2100

and have played lots of combination, no successful result.

note - there nothing in apache , php log file or exception occurring in php script cannot drill down issue coming.

edit:

i have noticed ajax not getting error, keep on waiting ever. if apache resetting connection ajax should receive connection reset error.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
