Hi Christian,<br /><br>
> We generated a core file, the output of the backtrace is:<br />><br />> (gdb) bt<br />> #0 0x00b237a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2<br />> #1 0x00b64825 in raise () from /lib/tls/libc.so.6<br />> #2 0x00b66289 in abort () from /lib/tls/libc.so.6<br />> #3 0x080c4436 in qm_free (qm=0x81677e0, p=0x0, file=0x811728e<br />> "proxy.c", func=0x811724e "hostent_cpy", line=187) at mem/q_malloc.c:444<br />> #4 0x0807e329 in hostent_cpy (dst=0x8266e28, src=0x8146134) at proxy.c:187<br />> [..]<br /><br>
Thanks for the backtrace, you could try the attached patch (for 1.5.x) if it solves the crash for you. The additional free after the loop looks indeed a bit suspicious.<br /><br>

We could try<br />> to fix this, but we're not sure about the sideeffects.<br /><br>
I also suspect the reason for the crash lays in this area. I did not wrote that module, thus i asked Daniel.<br>
