node.js - Determining the cause of RSS memory leak in NodeJS -


i stumbled upon memory leak in node.js application after migrating mongodb postgresql. code runs on node.js v 0.10.x. code , dependencies 100% written in js. i'm using pg.js module access database.

the problem see rss of node growing (until process crashes) not heap , not v8 external memory (logged via --trace_external_memory flag). that's why none of tools find leaks in v8 heap helping me.

what cause of memory leak? example, possible have leak related buffer instances wouldn't appear in external memory logs?

what version of postgres running? there memory leak in pre 9.3.3 versions relative json functions. 9.3.3 release notes:

"fix memory leakage in json functions"

if possible, try upgrading 9.3.3 or higher (9.3.5 recent stable release of writing).

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 .
