Limit the size of the header of a newsgroup to fetch

[Allen Yang]

Hi everyone,

I am not an expert of Gnus, and I found an annoying thing about
Gnus is that it will exceed the memory limit when fetching a
newsgroup which reserves a huge number of articles.

For example: 

In my case, there are more than 370,000 articles reside in a
newsgroup on the nntp server. Although I set only 100 when Gnus
asked me the number of articles to fetch before I entered this
group, Gnus still run into the trouble.

Is there any solution?
