Hello, I have problem with freezing FreeBSD boxes with PF on [zone: mbuf_cluster] = kern.ipc.nmbclusters limit reached last two months. But theres no evidence = (or I dont know, what I have to check yet) of huge traffic. If I can connec= t to server yet, I can see, that clusters are really exhausted: 206604/6681/213285 mbufs in use (current/cache/total) 206603/3697/210300/250866 mbuf clusters in use (current/cache/total/max) 206603/3640 mbuf+clusters out of packet secondary zone in use (current/cach= e) But why? How I can check what consume this memory? netstat -an, pfctlss -ss= shows nothing unusual. What I can check else? Another question - there are sins that freebsd 10.3 has different access to= manage memory clusters, as I can see on graphs over snmp. And last strange difference between 10.1 and 10.3 on graphs. First is the s= ame hardware, but freebsd 10.1, second 10.3.=20 https://postimg.org/image/5i7izm6rx/ https://postimg.org/image/j0efbwix9/ What else can I check? Thank you very much. Radek
