Fix, skip FTP retry in certain cases4.0.0-ONAP1.1.3
In certain conditions there is no reason to retry fetching files. For instance when the file is removed in the PNF or when the password/certificate is wrong. When the DFC is started there are sometimes queued VES events that referes to removed files which in turn results in that the DFC will retry fetching these files in vain. The DFC house keeps its number of concurrents tasks to not exeed quotas for memory,open file descriptors etc. As more threads are occupied with retrying, the fewer threads can do their intended work, which decreases the throughput. Testing has showed that already when the number of PNFs are 10, the throughput is radically decreased (and the problem is then escalating).
