Been working with Cisco gear since 2000. 4 years experience with Nortel DPN and Passport. 4 years experience with UNISYS DCP 50 (I know, WTF is that!).
Currently, working with Cisco R&S and wireless ... and tinkering with Asterisk.
Asterisk is now working and I've got Lenny enabled. Fun times ahead!

12.2(58)SE train is very, very buggy. You have three options: 1. Upgrade the firmware of the stack to either 15.0(2)SE or 15.2(4)E train; 2. Reboot the switches regularly; or 3. Do nothing and wait for the switch or stack to crash.

Would you actually trust PI to upgrade the firmware of your switches? I haven't and I would never recommend it. There are times when I used to upgrade >300 stacks per week by hand because PI and DNAC couldn't.

Raise a TAC Case and see if they can knock up a device pack for 3.5 or wait for the release of PI 3.7 (and pray it will be supported).

Reboot the 2nd switch and see if it improves. Otherwise, raise a TAC Case and see if you're hitting CSCvq25360.
