According to the recommendation I have migrated my Kamailio 4.1.2 to the Kamailio 4.1.3. But very frequent crashes are coming in Kamailio 4.1.3 which was not coming on the 4.1.2. The gdb backtrace of the crash is below:

I have seen many crashes in couple of days but the "data_lump.c: No such file or directory" this line is coming in every crash. I think every time it crashes in the same file and same function somewhere else.

Program terminated with signal 11, Segmentation fault.
