OK in fact it's different. Above we have a busy polling loop, which may
very be caused by the buffer space miscalculation bug and which results
in a process not completing its job until a timeout strikes. The link to
the other report shows a normal polling with blocked signals.
The processes that was created yesterday via soft reload, went 100% cpu
today.

this below :

epoll_wait(0, {}, 200, 0) = 0
epoll_wait(0, {}, 200, 0) = 0

epoll_wait(0, {}, 200, 0) = 0
is not good unfortunately. I'm assuming this is with 1.5.17, that's it ? If
so we still have an issue :-/
It is 1.6.3
