I am using qmail-ldap on FreeBSD 4.8. Recently, I found that there are
many processes hang in my qmail system for a long time. I have attached
the process with gdb and found something strange in side.
(gdb) bt

(gdb) l -

817 relayhost = 0;
818 for (i = 0;i <= host.len;++i)
819 if ((i == 0) || (i == host.len) || (host.s[i] == '.'))
820 if (relayhost = constmap(&maproutes,host.s + i,host.len -
i))
821 break;
822 if (relayhost && !*relayhost) relayhost = 0;
823
824 if (relayhost) {
(gdb) p relayhost
$16 = 0xbfbffd50 "??????\020??
(gdb) p host
$17 = {s = 0x0, len = 0, a = 0}
(gdb) p argv[1]
$18 = 0xbfbffdf1 "pbworld.com"
It seems that the stralloc_copys unable to copy the argv[1] into the
host variable.
Does anybody know what is this problem?
Thanks,
