Miners do not collect any Information when more than 128 nodes

Remo — Wed, 01 Aug 2018 16:55:00 GMT

Hello,

I have a problem with my minemeld server. Some days ago I reached 128 nodes (sum of miners, processors and outputs). If I do a commit with 128 nodes or more the minemeld process seems to keep restarting over and over. As soon as I reduce to 127 nodes or less it works again.

In the logs I did not find a lot ...

Is this an existing bug or is there at least a solution on how to get more than 128 nodes?

Thanks in advance for your help.

Hi @Remo

I already had this problem twice, but with two diagnosis. In both cases my MM kept restarting over and over. In the first case I added more memory to my VM and it stopped. But in the second case, my MM was not able to deduplicate IPs from many lists in the same Aggregator. Look the discussion here:

https://live.paloaltonetworks.com/t5/MineMeld-Discussions/Output-limit/td-p/210302

You could try both of them and report here the results.

Best regards.
