Description (partial)

Symptom:
Nexus switch experiences a process crash of "device_test". A core is saved and the switch remains operating (no reload seen). This crash does not appear to impact the switch.
<pre>
YYYY Month XX HH:MM:SS SWITCH_A %SYSMGR-2-SERVICE_CRASHED: Service "device_test" (PID 28882) hasn't caught signal 6 (core will be saved).
</pre>

Conditions:
Chassis: N9K-C93600CD-GX
Release: 9.3(3)

Frequency (Observations from 2 different switches, from 2 different customers): Issue was seen with 10-60 days of process up time, crash occurred with a large number of days between crashes (e.g. it didn't occur in rapid succession). 

Note: This the frequency was what was observed on the original cases, it doesn't indicate this is a hard and fast rule for all cases. Frequency could vary.

Impact: It doesn't appear this Bug results in operational impact to the switch. As long as the crash doesn't occur in rapid succession (multiple crashes over a short period) the switch will remain online without issue. It doesn't appear from previous cases that this process will crash with a high frequency.
