Valeu pela resposta Welkson mas infelizmente não resolveu. Alem do mais, o 
nmbclusters ta sobrando como voce pode ver abaixo:

netstat -m
386/769/1155 mbufs in use (current/cache/total)
384/402/786/25600 mbuf clusters in use (current/cache/total/max)
384/384 mbuf+clusters out of packet secondary zone in use (current/cache)
0/44/44/12800 4k (page size) jumbo clusters in use (current/cache/total/max)
0/0/0/6400 9k jumbo clusters in use (current/cache/total/max)
0/0/0/3200 16k jumbo clusters in use (current/cache/total/max)
864K/1172K/2036K bytes allocated to network (current/cache/total)
0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters)
0/0/0 requests for jumbo clusters denied (4k/9k/16k)
0/5/6656 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
0 calls to protocol drain routines

Tentei o mpd5 mas o resultado é o mesmo. A vpn até fecha mais rapido do que 
com o poptop mas sempre que trafega dados, a vpn cai com o mesmo erro.
