ValueError: Maximum allowed size exceeded while making SED #581

Describe the bug A clear and concise description of what the bug is. What data are you using and how was it obtained? I am using Fermi-LAT data of a source 4FGLJ0649.5-3139. During period MJD 55718-55802, I am getting this error while trying to generate the SED (rom 100 MeV to 300 GeV). While for other periods, I did not have any issue. It would be helpful if anyone could suggest what I could do differently or what might be the issue here. Thanks!

NOTE: This is for fermipy bug reports and not for questions about data analysis or issues with fermitools.

Hi! Can you try the same with ferry 1.2.2 installed via pypi. Also, can you send us a script that we can run to reproduce the error?

@ndilalla suggested also to try to ask for more memory when submitting to slurm at SLAC. It might be that the default is too small.
