Hi, After recent upgrade, FreeSWITCH was unable to start. During startup, it generates SIGSEGV, and terminated. I investigated, what happening, and found - problem was in the obsolete mod_file_string (see debug log below). I disabled load this module, and FS works OK. I think, need remove this module from the repository, or make another steps, for preserve this crash. Thanks, Oleg /usr/local/freeswitch/bin/freeswitch -u sip -g sip -hp -nonat Program received signal SIGSEGV, Segmentation fault.
