The FastCGI process exceeded configured activity timeout on shared hosting

I was using Godaddy asp.net shared hosting hosting the domain (mycampusnotes.com), everything was fine, until yesterday (15 April, 2015) at 4pm, I started to get these messages on my forum section of the website (http://mycampusnotes.com/forum and blog.mycampusnotes.com) [The forum loading time was fast since 10 months (around 2-3s), never had any issue since yesterday, no significant changes made in the code also]

Error link (snapshot containing 2 errors on 2 different subdomains) : http://i.stack.imgur.com/mXFq7.png

HTTP Error 500.0 - Internal Server Error
C:\Program Files (x86)\Parallels\Plesk\Additional\PleskPHP54\php-cgi.exe - 
The FastCGI process exceeded configured activity timeout

and then this error comes

HTTP Error 500.0 - Internal Server Error
The FastCGI process has failed frequently recently. Try the request again in a while

After that my asp.net code also started to affect

Timeout expired. The timeout period elapsed prior to obtaining a connection
from the pool. This may have occurred because all pooled connections were in
use and max pool size was reached.

But now it seems that the above asp.net issue is gone, and the php issue still resides, I couldn't understand that I haven't changed any of the code, the error started to come automatically without any changes in the code [the forum (mybb) and the blog(wordpress) section is installed by the app versions of the Godaddy]. Php is working on other sub domains and asp.net code is also working fine on other subdomains, but I am getting the above timeout error in both forum [mycampusnotes.com/forum] and blog [blog.mycampusnotes.com]. Any input from the community will be highly appreciated and helpful. Thanks ! I have already called godaddy 5-6 times, but it seems there is some difficulty in resolving the issue.

My subdomains are working fine, except the blog one [blog.mycampusnotes.com] and the forum is not working [mycampusnotes.com/forum].
