[Serdev] problem with recvfrom() in udp_rcv_loop()

[Andrea Bondavalli]

Hi all,

I am experiencing a problem related to the recvfrom() function
while receiving (with SER) an UDP message (REGISTER) on the port 5060.
The error reported by SER is the following:
ERROR: udp_rcv_loop:recvfrom:[11] Resource temporarily unavailable

The problem appears only for a particular UA that is sending these UDP
messages across a NAT.  At this time all the packets sent by such UA to SER 
are not received (they are all skipped) due to the same error.

Please consider that this UA is sending UDP messages also to a STUN
server running on the same host (http://sourceforge.net/projects/stun/)
and such server is able to receive correcly all the packets.
I'am running SER on a Linux box with kernel version 2.4.18-14.

Have you ever experienced a similar problem ?

Thank you in advance,
