" Java Heap Space" error

Zeeshan

Dear developing team of ProM,

I am running Multipercepective Process Explorer plugin using ProM 6.10. While running the precision/fitness mode of MPE for the event log with large number of events (but not many cases), I am getting the error of Java heap space. Below is the debug information. 

Petri Net is constructed using Heuristic miner and auto-mapping (event name with Life Cycle Transitions) is used. Kindly assist. 



Debug information is as follows:

Hi,

This means that ProM ran out of memory. Using the ProM Package Manager, you can set the amount of memory available to ProM. You can try to increase this amount, and then try again. Note however that the plug-in may just require more memory than is available on your machine. Theonly thing that then helps is reducing the size of the problem, that is, to reduce the complexity of the inputs somehow.

If the maximum is about 1 GB, then chances are that you are using a 32 bit OS or a 32 bit version of Java. In case of the latter, installing a 64 bit version of Java could help.

Kind regards,

Eric.
