Pointers have to uniquely identify a piece of "memory" (including mmap file) in memory. 32-bit pointer can only address 2/3GB memory (32bit = 2^32 = 4GB. Do I have to close these connections from server side as well?

The key is in understanding what it means when recv() returns zero. but if I don't use thread (change writefile() back to normal function), more than 15000 writes can be performed in 1 second!!

The key is in understanding what it means when recv() returns zero. In this tips-oriented article, learn the basics of POSIX threads, see how to identify and detect thread memory leaks, and get solid advice for avoiding them. It should be able to create more threads than that, especially on a 64-bit machine (is your program compiled with 64-bit pointers, though?) where address space fragmentation should be a non-issue. You can fix the leak by adding code to call pthread_join(), which joins each joinable thread.
