Actually, straceing the application up to the point where it gets its
first message like

[warn] Epoll ADD(1) on fd 13 failed.  Old events were 0; read change
was 1 (add); write change was 0 (none): File exists

would probably help if option 4 or option  is the case.  If you do
this, please send the strace and the debug log for the same run
together.  If it's more than 10 or 20 KiB, though, please upload it
somewhere and post a URL or send it to me personally?  I've got a
feeling lots of folks on this list don't necessarily want multiple
100KiB attachments.

peace,
