erlang - why gen_tcp:controlling_process() can failed with badarg? -


I have a problem with ejabberd module, it is http_bind but when I debug deeply, I found that socket and spelling After accepting the Hilling Process and when the GN_TPP: the process of re-signing for the receiver data for the new process received by the controlling process failed in Berang, why?

... 

  {ok, socket} = get_tcp: accept (summons), opts = [{active, false}, ...],% here proc_lib Function Return result: spawn_link (handler, ..) {OK, PID} = ejabberd_http: start ({gen_tcp, socket}, opts), gen_tcp: controling_process (socket, pid): {badarg, [erlang, Port_connect, [# port & lt; 0.140743856 & gt;, & lt; 0.5939.4350 & gt;]}, {inet, tcp_controlling_process, 2}, {ejabberd_socket, start, 4}, {ejabberd_listener, accept, 3}, {proc_lib, init_p, 5}]}

Any help? Most probably have crashed before calling for controlling the socket or process.

Why did they get crashed, I do not know, you have ensured that there is a process of ebbird, should it run?

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

I have a problem with ASP.NET MVC Ajax forms.

When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
