I am running into a situation where the nathelper module is causing openser/kamailio to crash. The crash occurs when opensbc sends and invite to openser with an extra CR in the message body. I already contacted the opensbc folks about this. I just wanted you all to be aware that this could cause serious service interruptions.
Error log:
kernel: [599650.771067] kamailio[25461]: segfault at 18 ip b7a0a6c7 sp bfbaaa70 error 4 in nathelper.so[b79f7000+18000]
Sample invite sent to kamailio.. Please look at the extra CR/LF after Supported. The nathelper module crashes after this.
