I'm getting the same thing. I'm using version 1.13.4 on Windows, from cygwin. Here's my command line:

wget -E -H -k -p -np --mirror -R txt,jpg,gif -i urls.txt

The file urls.txt contains URLs to sec.gov. I'm attaching the file so someone can reproduce the condition.

Wget will run for several hours (somewhere around 6 hours) before exiting with "out of memory" on my machine with 8 GB of RAM. It usually has processed 14,000 to 16,000 URLs at that point. However, in one case it had only processed 70 URLs (about 35 minutes).

There's clearly a memory leak. In the attached screenshot of the process from the Microsoft SysInternals "Process Explorer" tool, you can see the memory usage grow with each file. Some memory is returned, but some is not.

Possible clue: sometimes it exits saying "out of dynamic memory in yy_scan_bytes()".

I run Debian wheezy with linux image 3.2 on amd64 debian and when I try to run wget -qci <input file> as part of script for downloading pictures I get a giant memory leak.

Wget is on my system 1.13.4-3. Every time I start download of approx 200 pictures I get for 60 mb of download to disk,all together size of pictures, around 3GB size in ram of wget process.
I have searched but I dont see that someone else have had this sort of problem. Maybe it is not a bug I'm not sure, maybe its misconfiguration on my machine but I get that big leak every time I start wget in that script.

When I'm using wget for download from web and its started by other process like from firefox flashgot I have no problem with memory leaks.

Also to note I dont have a .wgetrc file at all. should I create it ? What to write in it ?
