I am using cisco_vpn_tunnel version 20220119.v0.3. I am observing that when IPSec uptime crosses 50 days then it doesn’t show more than 50 days. The value stuck in 49 days 17 hours. Here is the screenshot.
I am also sharing the OID of my device here below:
There are no 64bit counters for this value available. The maximum value this counter can have are 2147483647.
That means the maximum shown time would be 248 days.
If this device only shows 50 days then it is a firmware bug on the device.
From the definition of the MIB

looks like that cisco has reached the counter limit. The value point to the maximun of unsigned long integer. This is set by the cisco firmeware, and you should contact cisco for that reason.
