https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D206932 --- Comment #2 from Olivier - interfaSys s=C3=A0rl <software-freebsd@interf= asys.ch> --- Setting re0 to use a MTU of 9000 and the connection stays alive. Instead of timing out, the packet rate drops drastically once and things go back to normal.=20 The main difference in netstat is that the mbuf clusters are split between standard and jumbo frames ``` 768/2787/3555 mbufs in use (current/cache/total) 256/1524/1780/500200 mbuf clusters in use (current/cache/total/max) 256/1515 mbuf+clusters out of packet secondary zone in use (current/cache) 0/46/46/250099 4k (page size) jumbo clusters in use (current/cache/total/ma= x) 256/65/321/74103 9k jumbo clusters in use (current/cache/total/max) 0/0/0/41683 16k jumbo clusters in use (current/cache/total/max) 3008K/4513K/7521K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for mbufs delayed (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters delayed (4k/9k/16k) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile ``` The rate in vmstat keeps rising, but that doesn't seem to be a problem ``` interrupt total rate irq16: sdhci_pci0 1 0 cpu0:timer 3008083 1113 irq256: ahci0 10125 3 irq257: xhci0 11363 4 irq258: hdac0 3 0 irq259: re0 13105929 4850 irq260: re1 101440 37 cpu2:timer 1095578 405 cpu1:timer 1083354 400 cpu3:timer 1123144 415 Total 19539020 7231 ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
