[SR-Users] Kamailio 1.5.4 notls Core Dump

[Stagg Shelton]

  Kamailio 1.5.4 segmentation faulted today.  I was able to determine 
with gdb that the error occurred at mediaproxy.c line 1104.  Line 1104 
is a call to memcpy

Core was generated by `/sbin/kamailio -m 512'.
Program terminated with signal 11, Segmentation fault.
#0  0x00007f1469db6bb5 in replace_element (msg=0x77e470, 
old_element=<value optimized out>, new_element=0x7fffbd553210) at 
mediaproxy.c:1104
1104        memcpy(buf, new_element->s, new_element->len);

1.5.4 is new to our production environment, we were previously running 
1.5.2 notls (also no mediaproxy) for more than a year without issue.  
1.5.4 notls with mediaproxy has been running in our lab and 
preproduction QA environments since March of this year without any real 
segmentation faults.

Does anyone have any ideas of what may have caused this, or suggestions 
to get around this.  I do see that 1.5.5 is available, although there 
does not appear to have been too many changes to mediaproxy.c

Thank you in advance
