Have the same question - any feedback?

Hi All - We are hitting the same issue in our deployment. Upgraded MongoDB to latest build and started getting this issue. Anyone found any hacks or fixed "jar".

Hi Avinash Can you post your analysis here? Regards

@Hozawa - What is the method to find the memory required per report. How do we find out - are there any commands or logs to figure this out? Also, this problem does not manifest itself everytime we run reports. This only happens after a few days of execution ... what is the methodolgy to investigate such an issue?

Hi Experts I am new to Jaspersoft so kindly excuse me incase I ask very fundamental question. Jaspersoft Version: 6.4 MongoDb: 3.4 Objective: I have stored some timeseries data in MongoDB. My target is to plot this data in a line graph. Further, for one of the "columns" I will also like to plot another line which essentially provides the 95% percentile trajectory. Methodology Planned: Create a Scriptlet (Custom Java Class) that will collect all the values in the source Column/field and will provide a percentile output. Done so far: 1. I am successfull in using the Jasper studio to import and plot my timeseries data on a XY Graph. 2. Created following class be extending JRDefaultScriptlet: package net.sf.jasperreports.engine.mymethods;import net.sf.jasperreports.engine.JRDefaultScriptlet;import net.sf.jasperreports.engine.JRScriptletException;import org.apache.commons.math3.stat.descriptive.rank.*;public class class1 extends JRDefaultScriptlet{ public static double[] u_list = new double [1000]; public static int counter = 0; public double percentile(double u_value, double u_percentile) throws JRScriptletException { u_list[counter] = u_value; org.apache.commons.math3.stat.descriptive.rank.Percentile test = new org.apache.commons.math3.stat.descriptive.rank.Percentile(); double x = test.evaluate(u_list, u_percentile); return x; }}[/code] 3. Mapped a new Y Series in the graph with the following paramteres: $P{Scriptlet_2_SCRIPTLET}.percentile( (double) $F{Pre_Policy_BitRate}, (double) 95 )[/code] Problem: What I realised at the end of the excersize is that Jaspersoft re-instantiates the scriptlet class for every row of data. This really means that I never have more than one real value in my array. I was hoping that hte scriptlet would only create a single instance per report so that I can generate an array of numbers to feed my percentile method. Is this possible to acheive? Regards Deepak
