[sr-dev] git:kamailio_3.0: core: shm mem size can now be set in the config script

Module: sip-router Branch: kamailio_3.0 Commit: ecc3fd3f0599cf9fa1bb070970d730f4ab85675e URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=ecc3fd3… Author: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Committer: Daniel-Constantin Mierla &lt;miconda(a)gmail.com&gt; Date: Sun Jan 10 13:10:43 2010 +0100 core: shm mem size can now be set in the config script shm mem size can now be set in the cfg script using shm=size_in_mb, shm_mem=size_in_mb or shm_mem_size=size_in_mb. It must be set prior to any modparam or route block. Specifying the memory size on the command line (-m size_in_mb) will override the size from the config file.
