RE: haproxy hit 100% CPU

Hi Henry, that sounds like a very serious bug indeed. I suggest you take a traffic capture with a ring buffer and capture the exact frontend traffic. You can do this with dumpcap for example, something like should do it (if your frontend traffic is tcp port 80): dumpcap -i eth0 -p -s0 -b

Good Morning Will, Which version of haproxy are you running? I reported a very similar problem in 1.5-dev7 a year ago and Willy committed a fix on 20120109... has it reared its head again since? Joe http://comments.gmane.org/gmane.comp.web.haproxy/7108 -Original Message- From: Will

Re: haproxy hit 100% CPU

Hi Henry, I found the bug. It happens when hashing a parameter which is not found (typically an absent URL parameter) and then the connection to the selected server experiences connection retries, and the server goes down and up before the redispatching, and is the last server in the farm when

Balancing SIP

Does anyone have anything they could share about using HAProxy for load-balancing SIP? Positive /or/ negative, of course! :-) Jonathan

Re:haproxy in the sky

Haha, interesting job. I think the next step is to push haproxy to the open space and balance satellite traffic.

Haproxy multiple backend addresses ports

Haproxy and multipart/form-data

I'm having trouble getting haproxy to route multipart requests. Any help would be appreciated. The idea is to route all file uploads to a different server from the main. However, it doesn't seem to ever match the multipart in the request headers. I've tried hdr_beg(Content-Type) multipart and
