What version are you using? Is it from packages, downloaded from netxms web site or you compiled it yourself? What Linux version are you using?
Does it segfaults all the time, or it happened only once?
If segfaults repeat, can you set DebugLevel=9 in server config, launch the server and attach the resulting log file?
