lm_paypal subscribers status eot

I am using lm_paypal subscriptions to sell user role "friend". I have created three subscriptions single, couple and family, they differ in price only.

Now the subscriptions works fine at times but at other times the user role does not upgrade to "friend" and in the lm_paypal subscriber his/her status is "eot".

In the lm_paypal saved ipns there is no difference between the successful and unsuccessful subscribers but the logs generate the following:

Note: That the payment is successful in the paypal

Subscription Successful
