hi
almost all "gdb/bt full" contain:
#13 0x00000000005f916c in parse_disposition (s=0xa75468
tcp_reader_ltimer+228904, disp=optimized out) at parser/parse_disposition.c:60
disp_p =
new_p =
state = 2
saved_state = 2
tmp = 0x7f161b681fc0 ""
end = 0x4020dd8800000000 error: Cannot access memory at address
0x4020dd8800000000
func = "parse_disposition"A lot of tcp errors in kamailio.log before the crush.
How to solve the issue?

there are a lot of such TCP CRITICAL errors and the kamailio crushes

It is still not clear - what exactly causes such behaviour.
I want to recriate it in the lab - so what can cause it.?
May be a process erases the file descriptors of TCP connections?
Any help is appreciated.
