Servers upgraded, NFS not working as well

in flag

I administer two servers that were set up by a previous admin, one works as an NFS server the other the client and they have a dedicated 10GBase-T connection. Both servers were recently upgraded from Debian 8 to 11 per a requirement from management. The upgrades showed no errors that were TCP/IP or NFS related and before the upgrade the NFS connection was seemingly stable. After the upgrade it is no longer as stable with file access not working consistently. A check of the logs on the server shows two error messages.

rpc-srv/tcp: nfsd: got error -104 when sending 24 bytes - shutting down socket rpc-srv/tcp: nfsd: got error -32 when sending 24 bytes - shutting down socket

The -32 error shows up far more often than the -104 error. A check of the historical logs before the upgrade show the same errors though at a slightly less frequency.

Hoping for any assistance with this. A search found very few -32 errors in various forums, none solved, and some solved -104 errors but mostly via upgrades to an nfs-server version that has been superseded since then.

I will assume, that `-32` is `broken pipe` and `-104` is `connection reset`. To me sounds like network issue (firewall that drops idle connections?)

The servers are directly connected via 10GBase-T. There is no firewall or other device between them.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
