I've also reverted to 1.3.15.8 but seems to have the same issue. Not tried the
1.3.15.7 yet, I've compared sources and it seems the maxaccept behaviour has
changed. Tried to add tune.maxaccept 100 to the cfg with version 1.3.16, but
issue still occurs.
The epoll_wait / poll and gettimeofday is called too often:
% time seconds usecs/call calls errors syscall

I think so too, going back to version 1.3.15.7, cpu peaks at 2% with
the same load (about 10-20 concurrent sessions) and config.
/Sune
I am getting this also, on Linux 2.6.18 (CentOS 5) x86_64. Reverted to
1.3.15.7 and problem disappears.
Using a basic config doing simple http balancing.
