50% interrupt
-
I don`t know but I have 2.3 installed for 2 months and in a last week this issue popped up.
-
MSS clamping is on?
-
No
-
Something's beating it to death on em1 from the looks of it, the "100.00% [intr{irq259: em1:rx0}". Huge amount of load on receive. What traffic you see on that NIC? 'tcpdump -ni em1' on console while it's looking like that. em1 your LAN NIC or?
-
Yeah, em1 is LAN nic correct.
Funny thing is, there is NO traffic at all :)
-
What hardware's that?

Is this still replicable for you? Haven't heard of it elsewhere.

This happened 2X when I streamed video over ipsec.
Disabled hardware stuff in advanced settings and hasnt happened since. -

Could you please the friendly and tell us all exactly what you have done?
Perhaps it might be that others also find this useful and/or over Google as a solution. -
Disabled hardware offload, tso all 3 options in advanced section of the config…
-
Which of those did you have enabled before? The defaults, TSO and LRO off, hardware checksum offloading on, should be fine there.
-
I had all enabled:
Disable hardware checksum offload
Disable hardware TCP segmentation offload
Disable hardware large receive offload
