The problem is that your server sent article numbers that can't be read into an emacs int (they overflow). The bad article numbers are now part of the ".overview" file that the agent maintains for each group. To fix, try: 1) Put point in the group buffer on the group that can not be opened. 2) Do M-x gnus-agent-regenerate-group If that doesn't fix it, you can also search around for the ".overview" file then edit it manually. The article numbers are the first field in each line. For the file to be correct, the article numbers should be unique, small enough to read by emacs {you can use M-: (read (current-buffer)) to test individual numbers}, and in ascending order. BTW, the infinite loop between "finding keys" and "reordering" was reported yesterday. I should have a fix shortly. Kevin
