Claim Text:
1. A computer implemented method to preserve an inter-process connection between two endpoints during patching operations, the method comprising: suspending at least some communication activity for a client process such that an execution of the client process that corresponds to the communication activity for the client process is paused, while preserving one or more functioning states of the inter-process connection at least by saving information about the execution of the client process via the inter-process connection for later access after a patch operation is performed; implementing a wait state during which the execution of the client process is paused, and one or more incoming requests from the client process are blocked from execution until at least the patch operation is complete; producing a patched endpoint by performing the patch operation to one of the endpoints of the inter-process connection while the at least some communication activity remains suspended; and reconfiguring at least some of the one or more functioning states, which have been preserved, of the inter-process connection to connect to the patched endpoint.
