    copied!<p>I have problem with memory leak in nodejs when I added gzip support. I have wrote some code for tests. In code below I use zlib and I don't know why I have memory leak. How I can improve this code to avoid memory leaking ? Anybody can help me ?</p> <pre><code>var zlib = require('zlib'), crypto = require('crypto'); var cacheList = { article: {}, }; var timeoutId1, timeoutId2 console.log('process.pid: '+ process.pid); clean = function() { var time = new Date().getTime(); timeoutId1 = setTimeout(function() { clean() }, 5000); var countDeleted = 0; for (id in cacheList.article) { if (cacheList.article[id] &amp;&amp; cacheList.article[id].timeExpire + 5000 &lt; time) { delete cacheList.article[id]; countDeleted++; } } console.log('deleted: ' + countDeleted); </code></pre> <p>}</p> <pre><code> run = function() { var time = new Date().getTime(); timeoutId1 = setTimeout(function() { run() }, 5); var md5 = crypto.createHash('md5'); md5.update('' + time); var id = md5.digest('hex'); //console.log('id: ' + id); var text = id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id +id+id+id+id+id+id+id+id; zlib.gzip(text, function(err, result) { if (!err) { cacheList.article[id] = { timeExpire: time + 10000, data: text, datagzip: result, }; } }); </code></pre> <p>}</p> <pre><code> timeoutId1 = setTimeout(function() { run() }, 3000); timeoutId2 = setTimeout(function() { clean() }, 5000); </code></pre>
