Question on cisco prime, continuously losing connection to devices after config deployment

[hhhax7]

I am currently running a bunch of config deployments to a large group of switches. Every time I run one and get ready to run the next one, I would say about half of my devices lose connectivity. After a few minutes, everything comes back up and I can run the next deployment, but this delay is seriously slowing me down.

Anyone ever run into this issue before? I have reachability to the devices, but it says "SNMP connectivity failed". I don't believe its an issue with the password, because we have not changed anything there, and it does regain connection after a few minutes. Any other ideas?

you may run out of some resources on the appliance

- how much is "a large group" ? 

- how much devices in total

- do you have a hardware appliance or a virtual appliance?

- large medium or small CPI installation
you may set a maximum in parallel or even try deploying sequential instead of parallel

Large group consists of 50-70 switches (3750x)

Total devices is the same, running on all devices

Virtual appliance
