RecoverPoint for Virtual Machines: Purple screen after I/O Submission failure

Affected versions:     
RecoverPoint for Virtual Machines (RP4VM) Day One

Issue:     
Purple screen after I/O Submission failure

Impacted Configuration or Settings:     
esx_splitter

Impact on RP:     
The splitter frees the same memory twice, resulting in a Purple Screen

Root cause:     
An unexpected callback called from VMWare kernel for a failed I/O submission causes the CommandIo to be freed from both the dispatch path and from the callback. The expectation is that if the I/O submission failed, it will not get a callback, and the CommandIo would be cleaned up in dispatch path only.

Symptoms found in the logs:     
In the vmkernel logs, the failed submission (first two lines) is seen, followed by the unexpected callback context (last line):     

Resolution:     
Issue addressed in RP versions 5.2.2.4.0 and 5.3
