smbfs does not support file locking to the remote side. The local
processes will lock between themselves but not vs anyone on the server
side.

113 is "No route to host" (/usr/include/asm/errno.h)

This error leads to smbfs dropping the connection it had.

These errors look like random bits. There is no smbfs error code
4294967291. It can't validate that the file still exists because it no
longer has any connection and the new connection is not up yet.

-5 is -EIO. Same cause.

And then it reconnects to the server.

104 is "Connection reset by peer". Since you don't have any times on these
it's hard to say but it probably has nothing to do with the above. It
seems to be normal for a smb server to just disconnect clients when it
feels like it.

-26 = -ETXTBSY

smbfs usually fails to open files that others have opened.
