hi,

I don't think its network related as it usually happen when i subscribe just
after registration so i don't think its network related.

at first i thoght that its relate to having several subscribe at once so I
do them one by one and use the notify to drive this process.

I'll recheck again without this "feature" to see where it crushes more,
maybe this will give some hist into the problem.
