Methods and systems are provided for debugging application code in an on demand environment. The method includes executing the code on a server in the on demand environment; identifying a first location within the code having a suspected error; defining a first check point within the code corresponding to the first location; subsequently re-executing the code, including the first check point, on the server; creating a memory dump corresponding the first check point during re-execution of the code; and debugging the code based on the heap dump without suspending subsequent re-execution of the code.
