Ooh323 huge receive queue

I’m using asterisk on FreeBSD, and when I use ooh323 for my calls, I can see my recv-q count increasing to the point that my FreeBSD can’t get anymore packet and so i lose all access to it. during a call, when i get netstat I see something like this:

Active Internet connections
Proto      Recv-Q   Send-Q      Local Address          Foreign Address        (state)
udp4      201600        0                 *.7677                          *.*                    

I don’t have this problem using sip. Is it an ooh323 problem?

I’m not using gatekeeper. just two FreeBSD, and two soft-phones where soft-phones are connected to FreeBSDs via sip, and FreeBSDs are connected to each other via ooh323.
