How Many Graphs can run at once in regards to JAVA HEAP MEMORY

CloverDX Platform

Hello All,

I am experiencing JAVA HEAP MEMORY limits while executing multiple graphs at once. JAVA HEAP MEMORY is set to max 1820 MB but server is crashing in functionality when executing graphs. Anyone have any input on this scenario? How many concurrent graphs can run if the memory utilization for each graph exceeds clovers and JVM limits?

Hi Andrew

If a single graph has greater memory demands than maximum heap memory limit for the Server, then such graph cannot be successfuly run on said Server. In this situation you can increase the maximal heap memory size, but leave some of your RAM unallocated, and/or optimize your graph, so its memory demands would decrease. I cannot advise you any specific value of the maximum heap memory as it depends on complexity of the graph and size of the processed data. If you want me to help you with the optimization, please send me the graph and a sample of your input data. If the graph and the data correspond with your previous topic, it is ok to send them just once.

Best regards

Thank you for your reply. I just uped the heap max another 2 GB’s and that worked. Creating a temp CSV table of 4 mill rows was killing the memory.
