After upgrade appassure 5.4.3 to Rapid recovery 6.1, some snapshot failed

Question

Hi, I recently upgrade my appassure infrastructure to Rapid Recovery 6.1 
 After that, and after the upgrade of the agent, I have a lot of error like that 
 
 Transfer error 
 The transfer of one or more volume images from a protected machine to the Core has failed: 
 * Volume transfer failed: The transfer failed for volume 'C:\' 
 * Out Of Memory Exception: Exception of type 'System.OutOfMemoryException' was thrown. 
 
 Sometime is the C drive, sometime another disk. I don't know where to search to resolve that.

Hi guillaume, 
 
The RR software does require a bit more overhead to run. Could you give details on the Core server's system specifications? OS, RAM, other software and applications running on it is helpful information. 
 
Is the Core 100% up to date on Windows Updates? I have seen this error before, and completing all necessary Windows Updates resolved it. 
 
If the issue persists after Windows Updates, please come back here or open a support case so our team can look into it.

Hi Guillaume: 
 Just to add to the conversation, it makes sense to check the memory on your core to see if indeed all the memory is in use. If it is there is the possibility that the storage system has some issues and there is quite some amount of data that does not make it to the storage before all memory is taken. There are multiple causes for such a behavior. In the best case scenario you need to update both the firmware and drivers for all major components of your core. I recently had a customer who was running out of memory on the a high end core (and getting a dismal transfer performance) due to the older firmware for his 10Gb/s nics. 
 Other possibilities would be that some raid array is working with a bad drive or is rebuilding. 
 Other way of tracing the root of the issue would be the path you have taken to upgrade your appliance. To do it right (which I hope you did) is using the Recovery and Update Utility (RUU) v3.0.587 for DL Appliances from here On the same page there are links to newer drivers and firmware. 
 Only after installing RUU v3.9.587 and updating the drivers and firmware you should install (or re-install Rapid Recovery 6.1.0.645). 
 Hope that this helps.
