Re: Problem with function select on kernel 2.6.29.6-rt23

[Sujit K M <sjt.kar@gmail.com>]

Could you Check the sort of load that your server machine is able to
take. The site you would be looking at is
http://www.petefreitag.com/item/689.cfm.
I think if the network is rejecting the select call, As the socket is
not getting created. Other wise it would wait to the required 2 Second
limit set by you.
Also are you sure of the bind part of the socket creation. Making it
threaded is an option.

Thanks,
Sujit
