Thanks for postprocessing this. For the record, this composite survived a full t50 and a few thousand curves at B1=11e7. Just an ECM miss.

Default Well, that was quick (C205_924xx521_5)

Checked this morning to see no msieve process running, and worried that something had gone wrong over the weekend.

No: just a smaller calculation than usual

131^98+98^131 C253 cofactor seems stuck. All columns up to “Pending” keep increasing but nothing received.

Not sure what needs kicking but something seems not quite right. Greg issue?

Looks like a missing space in the polynomial file has caused the .ini file not to be constructed. Resubmitted.
