[galaxy-user] Trackster Error: needLargeMem: trying to allocate 0 bytes (limit: 100000000000)

I'm having problems getting Trackster working on my own Galaxy instance, so I thought I would check on the usegalaxy public server. However, I'm getting the same Trackster Error: needLargeMem: trying to allocate 0 bytes (limit: 100000000000) that was reported on this list in July, but there was no followup: http://user.list.galaxyproject.org/Trackster-Error-td4655737.html My history is at https://usegalaxy.org/u/simon-guest/h/trackster-error This is just an artificial test I made using a fragment of a reference genome, but I thought it should work OK. Any clues? cheers, Simon
