ERR#227 EADDRNOTAVAIL

Hi,

A program is failing. After tracing I found out that it failed due to the following issue:

--
getsockopt(9, 0, 0x2, 0x7fffe6ec, 0x7fffe6e8) ............ = 0
setsockopt(9, 0, 0x5, 0x7fffe6f0, 8) ..................... ERR#227 EADDRNOTAVAIL
--
Which means:
'Bad interface address for IP_ADD_MEMBERSHIP and IP_DROP_MEMBERSHIP.'
But I don't see what the problem is.
Can somebody help me?

Hi,
have you looked at:

Check your address ranges.

Hi Peter,

The code (java) is just doing a multicast to 237.0.0.1. And 237.0.0.1 is a valid multicast address as far as I know.
(I'm using hp-ux 11.23, Itanium)
