[SR-Users] Re: Kamailio stops processing the calls - restart fixes it.

Hi Daniel, Thank you for your valued input. There are several instances of redis set and get for example KSR.ndb_redis.redis_cmd("srvX", "GET " .. origid, "r"); and KSR.ndb_redis.redis_cmd("srvN", "SET cid-" .. KSR.pv.getw("$ci") .. " 1 EX 3600", "r"); etc. There is one incident in routing which does not occur frequently where lua script calls external php script os.execute("/usr/bin/php /usr/src/report.php " .. cid .. " 200 &") Also , in one specific condition lua script has to check if an existing dialog with the same called number exists. It forks external process to invoke kamcmd dlg.list local result = os.capture("/usr/local/sbin/kamcmd dlg.list_match turi sw sip:" .. tonum); Can any of this be harmful and be executed via libraries?
