Am facing a new problem with this GPRS communication. Since the communication is between 2 H stations, there are 4 UDP connections configured betweem CPU A & B of both the stations. Out of this two H station located at distant places, one station has less network coverage whereas the other staion has descent network coverage. At the station where the network coverage is less, the GPRS Modem(Scalance M873) is rebooting continously (LED's S, Q and C blinking in sequence) and never comes back to a stable state. And when i remove the ethernet cable connected to the local interface of the same GPRS modem(ie by isolating it from the local network), it is coming to a stable condition and the connection is getting established. And when i connect back the ethernet cable to the local interface port of the same modem, it again goes for rebooting and this continues until i remove the ethrenet cable connected to it again.

So is this because of the less network coverage? or is it because of a data traffic in the network? (note that the same amount of bytes(30 bytes) are transmiited from both the stations and this problem occurs only in the station where network coverage is less).

I have used for instances of AG_LSEND and AG_LRECV since four connections are configured which is initialized in OB1. I have attached the same for your reference. Kndly help me out with this issue at the earliest please. Your suggestions will be of highly helpfull.
