[SR-Users] kamailio 5.0.6 | segfault bad msg or missing FROM header

[Laurent Schweizer]

Hello,

Unfortunately I don't have the SIP signaling, they was no trace when it happens and I don't know the user that create this issue.

I will also check the memory just in case, but I think it's more a malformed  message.

Laurent

Hi,
As i see the dump.txt file, Please paste the SIP signalling to check more. As the log, the From header may be malformed syntax.
because when parsing the From header, the issue is occurred. This error is raised  when Form header isn't parse properly.
Also check the shared and private memory. May be in while parsing the sip message, "out of memory"  is occurred to.
Whit Regards.
