Hello,
I've been dumping a fairly large database with sqlmap over the past week, and I
have ran into a problem trying to resume the dump. It's running out of memory
and killing the process. The output/xxxxxxxx/session file is 1.1GB, and the
system I'm duping it with has 4GB of ram. From what I can tell, the python
code is loading the entire file into memory, rather than reading it
line-by-line which is why it's dying. I looked in /var/log/kern.log (I'm
running Ubuntu) and it shows that it's simply running out of memory.
This is 100% reproducable now, and happens every time I run it.
[19:14:58] [CRITICAL] unhandled exception in sqlmap/1.0-dev (r4381), retry your
run with the latest development version from the Subversion repository. If the
exception persists, please send by e-mail to sqlmap-users@lists.sourceforge.net
the following text and any information required to reproduce the bug. The
developers will try to reproduce the bug, fix it accordingly and get back to
you.
