The SNMP query engine attempted to read the extended length field of the ASN.1 type but could not find the data to read.
Run traces to determine whether the error is in the incoming presentation stream or in the SNMP query engine translation process. If the presentation stream is in error, contact the support center of the client or agent originating the request. If the SNMP query engine is reading the presentation stream incorrectly, contact the IBM® Software Support Center.
