Petascope internal error when run wcst_import in batch import

[Bang Pham Huu]

I'm testing wcst_import.sh in bash script inside a loop to ingest a multiple coverage (each recipe file has different coverage id).

for i in $(seq 1 $NUMBER_BANDS); do
  wcst_import.sh $INGEST_FILE
done

When run script, I access some WCS services like GetCapabilities or DescribeCoverage and get some error from Petascope internal, such as

<ows:ExceptionText>
org.postgresql.util.PSQLException : This connection has been closed.
</ows:ExceptionText>

using wget to check HTTP code, I almost see when ingesting data, it will returns error 500.
