           Summary: spamd core dumps when loading full uri file from
                    passwall.com
           Product: Spamassassin
           Version: 3.1.0
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: critical
          Priority: P5
         Component: spamc/spamd
        AssignedTo: dev@spamassassin.apache.org
        ReportedBy: jrapps@bloomberg.net


spamd core dumps (segv) when I try to include http://www.passwall.com/uri.txt. 
I installed it under etc/mail/spamassassin as a .cf file. The file is some 190k 
lines. I played with the size of the file to see the max size it would handle, 
which was around 182k lines. Is there a tunable I am missing? thanx.

Hrm.  Well, 3 thoughts for you.

1) If you're not simply running out of memory (and sig11 is perl's way of telling you "out of memory"), 
you could have an issue with your perl binary or a module's XS code -- but that's not SA-related (we 
don't do XS).

2) 190k is huge!    The core SA rules files for development are only 9.4k.  There's no reason, in theory, 
why you couldn't use a config that large, but I doubt any of us have tested something like that, and it's 
not clear what the resource usage is going to be.  

3) Related, what you're trying to do could be much more easily done through a plugin or by building 
your own URI blacklist via DNS then just querying that.  For the same reason people gave up with 
BigEvil, etc.

I'm leaving this open because perhaps it will turn out that something can be
changed to allow SpamAssassin to work with something that big, and maybe it
would introduce efficiencies in more common configurations, but I think you are
taking a fundamentally wrong approach. I tried to use the file with version 3.0,
and while it did not crash, it really bogged it down.

We already support URIRBLs and there are people running servers for them.
Someone should talk to passwall.com and see if they would save themselves some
bandwidth by putting their list on a DNS server or even if they would talk to
the people at surbl.org about submitting their list there.

Even if passwall.com doesn't do that, a simple script should let you convert
their  SpamAssassin rule file into input for your own DNS server to use as a
custom local URIRBL zone.
