change of polling engine

[Valentin V. Bartenev]

Hi,

I think it would be better to find out what's wrong in case of epoll.
Could you share a debug log with the issue?

Note, that some time ago we finally dropped Solaris from our testing builds
due to constantly increasing burden of maintaining its support.  So, I'm not
sure that eventport code is still in a good shape and able to function well.

Also, the issue can be irrelevant to the event method.

  wbr, Valentin V. Bartenev
