Check the "debugSignal.txt" file sitting inside the ASSP folder; if possible, enable debugging options in ASSP, those should help pinpointing the cause for the crash and possibly solving the issue as for the remainder... > CPU is around 60% and is using 800mb of RAM. > Current filter I am using: Validate HELO, DNSBL and URIBL > Numbers of threads: 5 Please tell us more about the system (RAM, CPU...); also, if you are using the OCR module, please *disable* it (at least until the issue won't be solved) since that one alone may add some huge load on ASSP; if you need to filter "image spam", you may then use some additional clamAV signatures like the ones found here http://www.sanesecurity.co.uk/databases.htm as for the checks and the settings, if you have enough memory, try setting up ASSP so that it will be able to automatically increase the workers if needed, also, enable the graylisting, the automatic spam trap generation and the penalty box (and IP profiling); ensure that ASSP has fast DNS resolution; possibly install a local DNS resolver like, for example http://www.unbound.net/ (lighter and faster than the regular BIND) and set it up to use root-hints and recursion avoiding forwarders; if that won't suffice yet, you may try adding this "trick" to your setup http://www.mail-archive.com/[email protected]/msg51583.html so that some of the junk hitting your ASSP will be "routed" elsewhere ------------------------------------------------------------------------------ _______________________________________________ Assp-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/assp-user
