We faced many problems during these days but the most difficult one, was when we were integrating our Cbuilds job portal with Cbuilds main server page, where our application has been crashed 4 times and we were sucked for at least 3-4 hours to solve that. Merging two different servers is not an easy task but after soo much of debug, we tried many hacks among which one worked by sending port details to another portal, which sounds easy but hard to implement, as we worked in a team and finally solved that problem.
