It would be nice to know what kind of client is triggering this. If you
go back into "gdb", then run these three commands:
fr 6
p hostname
p sender

(gdb) fr 6
#6 0x0805d82c in main (argc=1, argv=0xbfc5e484) at xymond_client.c:2166
2166 os = get_ostype(clientos);
(gdb) p hostname
$1 = <value optimized out>
(gdb) p sender
$2 = 0xb76f8817 "142.150.160.218"
Should I rebuild with -O0 as opposed to -O2?
Ok, the problem here is a host sending some "client" data without a
valid hostname or operating-system identifier. A client message should
begin like
client jorn,hswn,dk.linux linux
Well, the entry in /var/lib/xymon/hostdata looks ok from that POV (here
are the first few lines):
[collector:]
client devonian,utsc,utoronto,ca.sunos sunos

[uname]
SunOS devonian 5.10 Generic_138889-02 i86pc i386 i86pc
