Summary: Site-to-site with large files: "Site2Site transaction xxx peer unknown respond code 14" Key: MINIFICPP-2287 URL: https://issues.apache.org/jira/browse/MINIFICPP-2287 Project: Apache NiFi MiNiFi C++ Issue Type: Bug Reporter: Marton Szasz It looks like nifi may have extended the protocol, and minifi c++ didn't follow the development. >From the nifi slack: >[https://apachenifi.slack.com/archives/CDF1VC1UZ/p1705327811015419] {quote}Running minifi c++ v0.15, I am getting errors when transferring large files (10gb) via site to site to a Nifi (v1.20) cluster. Per the logs,the transfer is on going for a while (warning logs, inputPortName has been running for xxxxx ms in \{connection ID} then it looks like the transfer completes (info log, Site to Site transaction ... set flow 1 flow records with total size xxx-yyy-zzz ) ALSO, the large file appears on the remote Nifi cluster then it looks like the transfer failed (warning log, Site2Site transaction xxx peer unknown respond code 14) then another error, (warning log , ProcessSession rollback for inputPortName executed ) the finally, (warning protocol transmission failed, yielding ( xxx-yyy-zzz )This results in endless copies of the large files as presumably minifi retries the file despite successfully transferring the file.The logs show that other smaller files continue to be transferred while the large files yield.
