poll: unexpected event 24

Hi,
i am running heavy loaded server and had overload problems (average was load 10-30 when 300-400 apaches was running).
Then I installed mathopd and with apache's mod_rewrite rewriting pictures and movies path to another port (8080) where mathopd is running.

Everything seems to be OK now, but some people say not all pictures load. I installed yesterday's new beta and now i see all pictures and people too. 

The problem is that I get error messages that i would like to translate to avoid any problems.

Please advice what is:

Thank you in advance,
