on a very long bench > 24h with a monitoring taken twice by second, the fl-build-report failed to create an html report. During the monitor chart creation we got a segfault:
Creating html report: ...Segmentation fault
this happens during the gdchart call, perhaps the amount of data is too big for gdchart.
a temporary workaroud to have a report without monitor charts is to remove monitor element from the xml result:
cat result.xml | grep -v '<monitor ' > result-without-monitoring.xml
then build the report
fl-build-report result-without-monitoring.xml --html
