H2 recv headers compression errors

[jvgutierrez]

On the last few days our Singapore DC has been experiencing an increased error rate for "HTTP/2 connection error recv headers compression":

vgutierrez@cp5011:~$ journalctl -u trafficserver-tls --since="1h ago" |grep "recv headers compression error" |wc -l
24100
vgutierrez@cp5012:~$ journalctl -u trafficserver-tls --since="1h ago" |grep "recv headers compression error" |wc -l
28128

this hasn't spread (yet?) to other DCs but it seems pretty worrisome, have you seen anything similar?

FWIW, on 9, we've seen this around 1500 times over 7 days, across our fleet. 80% of those are from one source IP.

We're on 9.1.x. On a single box I'm looking at, I only see about 100 for about an entire day. Some days less. The box does about 5,000 requests per second. I confirmed with ops that none of our boxes are seeing that volume of these.

I am seeing around 1000 such messages in 5 mins... mostly from taiwan region
