Agent 1.4 net.if item supported if dont exist

[juampe]

Using templates, I supose if a element don't exist agent returns ZBX_NOTSUPPORTED
and ZBX forget it. But I found a case that agent returns some trash and the item is showed as supported.
The followting host does not have cip0 or hme0, but eri0 does

I neet someone help me to dig into source

I believe tha the following code is related to the problem.I dig into it an aparently is all OK.
libs/zbxsysinfo/solaris/solaris.c
libs/zbxsysinfo/solaris/net.c

Someone can give me a quick workflow about how agent get and print a item?

gdb to the problem

I'm going closer to the problem's root.
The unwised output comes from gdb 314 if(result.type & AR_UINT64) in zbxsysinfo/sysinfo.c

(result.type & AR_UINT64) and (result.type & AR_MESSAGE) are true at the same time

process (in_command=0x374b8 "net.if.out[eri0]", flags=1, result=0xffbfe7f0) at sysinfo.c:517

(gdb)
525 err = NOTSUPPORTED;
(gdb)
