I am a PhD student with an interest in all things programming. In my day job, I use numerics to obtain new results in General Relativity.

Series command no longer expands arbitrary functions after aborting previous evaluation Thanks, but I highly doubt it's related to that. I'm not trying to expand array of expressions, plus, both Series and SeriesCoefficient worked fine until now. (And they still do if I start fresh kernels). I guess there's not much I can do at this point other than restart and hope it doesn't occur again. |

Series command no longer expands arbitrary functions after aborting previous evaluation I've underestimated my expression. The culprit seems to be over 20000 lines long and I couldn't find a pastebin that wouldn't choke on it. If anyone's interested I've uploaded it in the form which can be quickly imported using MetricFG13=(<<"MetricFG13");. The command which caused the problem was SeriesCoefficient[MetricFG13,{\[Xi],0,4}]. (I think I let it run for something like 20 minutes before aborting.) |

Series command no longer expands arbitrary functions after aborting previous evaluation MathKernel is using just over 580MB. My system still has just under 4GB available though. |

Series command no longer expands arbitrary functions after aborting previous evaluation @rcollyer These are terms in asymptotic expansions of a curvature tensor in high dimensions, some of them are many hundreds of lines long and take hours to extract. Unfortunately I don't think I can reasonably paste the code which will duplicate my expressions in this space. I understand that I'm not making it easy for people to reproduce this condition, but I thought there might be some attribute which causes Series to avoid processing arbitrary functions. |

Unsaved notebook is crashing: is there any way I can save the state of the MathKernel before I kill it? I have coredumped the MathKernel and Mathematica processes in question and duly forced the crashing instances to close. I've re-done all my work, but if anyone knows an easy way to extract inputs from the dump (which is around 1.6GB of binary content) that'd be a great prevention against future crashes :) |
