Dunno if this could be considered a bug...it was certainly not what I expected though...
I have configured multiple server aliases.
1 to only be used for downloads of bodies
1 to only be used for searches
2 to be used for header retrieval
I have configured NL to only retrieve 50000 headers per update (for the large groups)
When I checkedmarked two large groups, I expected that the two connections configured to retrieve headers, would each take a group and fetch 50000 headers from each group...or split the 50000 per group over the two connections
instead both connections fetched 50000 headers per connection from the same group, before continuing with the second group and each connection again fetching 50000 headers. twice the amount I had configured.
