A method, system and computer program for dynamically updating code managed by an authorized agent. The method includes executing multiple versions of agent code in system memory. One version of the agent code is executed as an active version and another version of the agent code is executed as an inactive version. Version numbers of the active and inactive versions of the agent code are stored in a reloadable module vector. Client instances previously bound to the inactive version of the agent code are bound to the active version of the agent code after comparing the version numbers of the active version of the agent code and the inactive version of the agent code. A portion of the system memory used by the inactive version of the agent code is deallocated when no client instances are bound to the inactive version of the agent code.

Dynamically updating code without requiring processes to restart

A method for automatic throttling of work producers by actively monitoring the amount and rate at which work is both produced and consumed relative to a threshold value, the consumer thread can calculate the subset of the 'N' threads which can be placed in a temporary sleep condition, wherein the duration of sleep is determined to give the consumer thread processing time to catch up, keeping the process from being overrun. 'N' is the number of unique producer threads.

Method for automatic throttling of work producers

A method for safely interrupting blocked work in a server including: creating a registry; registering a potential blocking event in the registry; executing the potential blocking event; determining that the potential blocking event is not responding; accessing a registry entry corresponding to the blocking event; and taking an corrective action indicated by the registry entry corresponding to the blocking event.
