RPC Time Limits
A public READ/WRITE property (i.e., RPCTimeLimit) allows the application to change the network operation timeout prior to a call. This can be useful during times when it is known that a certain RPC, by its nature, can take a significant amount of time to execute. The value of this property is an integer that cannot be less than 30 seconds nor greater that 32767 seconds. Care should be taken when altering this value, since the network operation will block the application until the operation finishes or the timeout is triggered.
There is also a Server time limit for how long to stay connected when the client doesn't respond.
