I've just installed leech (http://leech.mozdev.org/) and am already a fan of the
tool :-)) !BUT! I discovered the following issue :

leech works by passing all downloadable links to the download manager by writing
directly to the download manager thus bypassing the normal "Save Link Target As..."

Now, I had a dowload page with eg 9 links pointing to *.rm files.
As observed in the download manager the download manager started 8 parrallel
downloads. One completed and the 9th started. When 4 downloads had completed
successfully, the remaing 5 stalled.

I tried several times, with the same result, but in each case the 4 completed
downloads were different files.

This is only an issue with big files -- the download manager and leech will
happily conspire to download a hundred or more *.jpg files in the 100kB range

Reproducible: Always
Steps to Reproduce:
1. install leech (http://leech.mozdev.org/)
2. find a page with a lot of +MB file downloads
3. open download manager
4. leech the files

Actual Results:  four out of X downloads complete

Expected Results:  all downloads ought to complete

this is also seen on Mac OS X 10.1.5

I'm unable to give an URL as the site in question is password protected and
subscription based. Furthermore, the site in question uses cookies to controll
authorisation of downloads, thus diabling the possibility of using an external
download manager - and I've tried both iGetter and Monica under both Mac OS 9.1
and Mac OS X 10.1.5

I'll try to set a test page up

workaround:
use "Save Link Target As..." for large files and download them one-by-one
waiting for each download to complete

a) Are you downloading this files from the same server ?
b) Do you have enough space in your temp directory ?

Comment 2

[Bjarne D Mathiesen]

answering questions :
a) all downloads from same server
   the latest 100kB range *.jpg download downloaded 284 *.jpg's perfectly

b) cachesize:
-- memory  4096
-- disk   50000

I did some further testing on the diskcache:
-- 75000 : the situation actually worsened
   only 3 files got completely downloaded 
   AND they weren't transferred out of the disk-cache
-- 0 ; 25000 ; 50000 : in all three cases behaviour as originally described

resolving
issue has fixed itself implicitly in
-- Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.2b) 
-- Gecko/20021016 MultiZilla/v1.1.21

adding testsite

has been tested as WFM
-- locally on lan
-- externally with 24 *.rm files in the range 1MByte - 6MByte
on both MacOS X 10.2 and MacOS 9.1
