Hi!
Thanks for using SPMF. This means that the algorithm is running out of memory. To avoid this problem you may try increasing the "minsup" parameter of FPGrowth, or using the maximum pattern length constraint (see the documentation). This will reduce the number of possibilities and the algorithm will run faster, use less memory and find less patterns.
The problem is that in itemset mining, the search space exponentially increases usually when you decrease the "minsup" threshold. Thus, I recommend to start with a high value and to see if it runs, and then to decrease it until you find enough patterns.
20k transactions is not a lot. But if the minsup threshold is set too low, the search space can be huge!
If you use the maximum pattern length constraint, it will also reduce the search space a lot and help you to get results more quickly and reduce memory usage!
Best regards
