Package: ndoutils-nagios2-mysql
Version: 1.4b6-2
Severity: normal
Hi!
I've just set up nagios2 and ndoutils (via apt-get -b source), and in
trying to import old logs came across the following bug, which only seems
to occur when trying to import already-imported log entries.
gdb output:
(gdb) set follow-fork-mode child
(gdb) run -c /etc/nagios/ndo2db.cfg
Starting program: /usr/sbin/ndo2db -c /etc/nagios/ndo2db.cfg
Failed to read a valid object file image from memory.

dbhandlers.c:555 reads:

fo.last_logentry_data)){
#ifdef NDO2DB_DEBUG
printf("IGNORING DUPLICATE LOG RECORD!\n");
#endif
return NDO_OK;
}
So I'm guessing that whatever the hell this C-construct
"(es[0]==NULL)?"":es[0]" is supposed to do ain't what it actually does.
Via strace it looks like
