https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206932 --- Comment #2 from Olivier - interfaSys sàrl <software-freebsd@interfasys.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. 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/max) 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 ``` -- You are receiving this mail because: You are the assignee for the bug.help
