Description (partial)

Symptom:
A Nexus switch might generate a VSH core file when running "show logging log" command and using  "Ctrl+\" to quit the output.


2020 Jan 17 06:32:15 NEXUS2 %VSHD-2-VSHD_SYSLOG_EOL_ERR: EOL function syslog_show from library libsyslog.so exited due to Signal 3
2020 Jan 17 06:33:20 NEXUS2 %SYSMGR-2-LAST_CORE_BASIC_TRACE: : PID 31764 with message vsh(non-sysmgr) crashed, core will be saved .

Conditions:
When running "show logging log" command, "Ctrl+\" is used to quit the output. This causes VSH to exit and generate a core file.


This is an expected behavior since 'Ctrl+\' generates a quit signal that terminates VSH process.
