Kerberized mounts (sec=krb5) exceeding 31 NFS directories fail
This document (7009341) is provided subject to the disclaimer at the end of this document.
SUSE Linux Enterprise Server 10 Service Pack 4
Mounting less than 31 NFS directories with sec=krb5 is possible.
It is also possible to mount more than 31 directories with the sec=sys option.
Only NFS mounts beyond 31 directories with sec=krb5 will fail.
Restarting gssd with -vvvvv does not provide any output.
The following is written in /var/log/messages:
"kernel: RPC: AUTH_GSS upcall timed out"
Increasing "#define FD_ALLOC_BLOCK 32" to 256 resolves the problem.
The SLES10 SP4 nfs-utils update, nfs-utils-1.0.7-36.44.1 released November 2011 includes the solution to resolve this problem. Please install the recommended update.
Customers with SLES10 SP3 and Long Term Service Pack Support can contact SUSE Technical Services to request a PTF (temporary fix).
