# Name : collect_errors
#
# Description: search COLLECT_ERROR_LOG for "No space left on device" logs
# Return 0 if no such logs are found.
# Return 1 if such logs are found
#
# Assumptions: Caller should assume a non-zero return as an indication of
# a corrupt or incomplete collect log
#
# Create logs and screen echos that record the error for the user.
#
# May look for other errors in the future
