Re: [Pan-users] Groups w/huge header count won't load?

[Jim Henderson]

Presumably, you don't need to read all of the million plus messages in the 
group.  I have groups that have in excess of 400,000 messages myself that I do 
occasionally reload for testing purposes.

What I have is a couple of rules and a behaviour I use:

1.  Rule to delete messages > 30 days old.
2.  Rule to delete messages in really large groups > 14 days old
3.  When downloading for the first time, select all groups, right-click, and 
select "Download nnn headers", fill in a value of something like 5,000 messages.

There are performance issues in 0.14.2 with larger groups because of how the 
database structure pan uses works (at least as far as I know, I don't do 
development on it).  Lots of memory helps if you need to pull all of those 
messages in.

Subject: [Pan-users] Groups w/huge header count won't load?

Ok, so I switched completely over to SuSe 9.1 from Windows XP
SP1.  Finally Linux was ready for me. ;-)  I couldn't find a news
reader for KDE that worked with binaries, so I grabbed Pan and,
having run into touble, have arrived here.

When I run a "Download all headers" operation on a group with a
large volume of headers (like a million +/-), everything is
fine... until Pan is almost finished downloading the headers.

According to the program's status bar, it'll get to within a few
headers of downloading all available headers.  Then the harddrive
proceeds to thrash away, like something's being processed.  If I
look in Pan's Task Manager, it says the headers are still being
downloaded, despite there being no network activity (I guess the
status bar's display simply hasn't been updated by this point?). 
If I look at KDE System Guard, swap file useage is in the 400-600
MB range.

I've tried leaving the machine alone to process the headers for,
like, 8 hours at a time, and Pan never manages to parse them
properly.  If I close Pan and restart it, I'm prompted to resume
the last batch, at which point Pan proceeds to download all the
headers from scratch.

So, can anyone help out here?  Is this a known issue?  My problem
is probably related to this guy's :
http://lists.gnu.org/archive/html/pan-users/2004-05/msg00030.html
, however, the details of that thread don't exactly match-up with
my situation.

I really hope I can get some help here.  Pan is the only viable
alternative for Usenet on Linux ATM.  Usenet is a killer app for
me and, if I can't resolve this issue, I may be forced to run
back to Windows. :-(  FYI, I'm running Pan v.0.14.2.91 on an
Intel-based system with 384 MB RAM.

STIA,
Keith, Ottawa
