Package: nfs-kernel-server
Version: 1:2.8.3-1
Severity: normal
Dear Maintainer,
I'm using SysVrc and updated an NFS server from Deb12 to Deb13. This is a
machine which heavy load due to Veeam Backup & Replication repositories.
To keep up, I had changed /etc/default/nfs-kernel-server to increase
RPCNFSDCOUNT to a number high enough to stop syslog messages about
incomplete data transfers.
Since Deb13, RPCNFSDCOUNT is no longer used. Culprit is that in
/etc/init.d/nfs-kernel-server lines 99 to 101, /sbin/rpc.nfsd is
no longer given the $RPCNFSDCOUNT variable, as it was in the Debian 12
initscript.
