["Salih Gönüllü" <sag@open.ch>]

Hi,

ulogd2 is segfaulting upon receipt of sigint or sigterm


Program received signal SIGTERM, Terminated.
0xb78c4430 in __kernel_vsyscall ()
(gdb) cont
Continuing.

Program received signal SIGSEGV, Segmentation fault.
0xb78b71ba in main_arena () from /lib/libc.so.6
(gdb) bt

I have tried with beta4 and with git 
4f652cc32aebeac20f46009f146ad973a1ed0e99


Is there a way to avoid this ?

#ulogd.conf

stack=log2:NFLOG,base1:BASE,ifi1:IFINDEX,ip2str1:IP2STR,print1:PRINTPKT,emu0:LOGEMU


[log2]
group=42
