zmstat-chart java.lang.OutOfMemoryError

[jummo]

I would like to generate advanced statistics with zmstat-chart. But the zmstat-chart utility abort operations at Reading CSV allprocs.csv with the following error.

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
        at java.util.Arrays.copyOf(Arrays.java:2734)
        at java.util.ArrayList.ensureCapacity(ArrayList.java:167)
        at java.util.ArrayList.add(ArrayList.java:351)
        at java.util.regex.Pattern.split(Pattern.java:1003)
        at java.util.regex.Pattern.split(Pattern.java:1059)
        at com.zimbra.common.util.CsvReader.hasNext(CsvReader.java:66)
        at com.zimbra.perf.chart.ChartUtil.readCsvFiles(ChartUtil.java:856)
        at com.zimbra.perf.chart.ChartUtil.doit(ChartUtil.java:342)
        at com.zimbra.perf.chart.ChartUtil.main(ChartUtil.java:308)

After some research, I have added -XX:-UseGCOverheadLimit to /opt/zimbra/bin/zmstat-chart at the exec line. Then zmstat-chart ends up with the same error, again at Reading CSV allprocs.csv, but it takes more time to run, of course.

Thanks in advance

Bump. I have the same problem.
