Using long lines of base64 text with isc_info_svc_line is useful when dealing with trace plugin in order to transfer actually binary data to the client. This may appear strange choice but it helps to make trace process better interactive at the same time using single packet per trace event. But currently services manager is not ready for long (>=1Kb) lines transfer, causing need of strange code on client to process such packets and network traffic overhead (more packets than really needed).
