Despite the importance of threads in modern computing, they are known to have drawbacks:

Programming mistakes are very expensive. If one thread crashes, it brings the whole server down. One rogue thread can corrupt the global data, causing other threads to malfunction.

Programming mistakes are easy to make. A programmer must think constantly about the possibility of some other thread doing things to cause trouble, and how to avoid it. An extra-defensive programming approach is required.

Threaded servers are notorious for synchronization bugs that are nearly impossible to duplicate in testing but happen at a very wrong time in production. The high probability of such bugs is a result of having a shared address space, which brings on a much higher degree of thread interaction.
