So you are seeing CPU spikes at 100%, about fifty/fifty between
system (kernel) and usr (haproxy).
Which OS and kernel are you using?
Can you post more configuration (not just timeouts)?
Are you using SSL?
Are you using nbproc?
Can you post the output of haproxy -vv?
You are saying the this happens after an upgrade to 1.6.2 or 1.5.15.
Which release did you use previously that worked fine? Did you
only upgrade haproxy to a new release or did you do any other
changes as well (config changes, OS/kernel changes or tuning)?

Lukas
