Re: (nfnl_talk: recvmsg over-run) and (nf_queue: full at 1024 entries, dropping packets(s). Dropped: 582) - bug or just some defaults increase required?

Pablo,

Some more info. After applying the patch, If we do try to 
just create 100 QUEUE's by the test code - on the test PC, 
with _no_ transit traffic, routed to QUEUE's - it works 
fine, queues created with no problem. 
But if we do this on the live PC, with trasit traffic routed 
to queues - we came to the problem once in a few queues. 
We localized the place, and the sequence is as follows:
nfnl_query=>nfnl_catch=>nfnl_process

and in the nfnl_process

if (nlh->nlmsg_seq && nlh->nlmsg_seq != h->seq) {
                errno = EILSEQ;
                return -1;
}

and varibales are
nlh->msg_seq=1234422225, h->seq=1234422229.

EILSEQ=84
strerr(84) returns "Invalid or incomplete multibyte or wide 
character"

Any clue on this?

Regards,
Anton.
