APAR status
Closed as program error.
Error description
Accessing an automounted directory with -hosts map where the NFS server has more than 50 exports can cause the command (ls, cd etc) to hang. This happens only with -hosts map and not with direct or indirect maps.
Local fix
Limit the number of exported directories on the NFS server to be less than 50 (This number also depends on the length of the pathnames, so longer pathnames means even fewer directories that can be exported)
Problem summary
Accessing an automounted directory with -hosts map where the NFS server has too many exports(approximately around 50 exports) can cause the command (ls, cd etc) to hang. This happens only with -hosts map and not with direct or indirect maps.
Problem conclusion
Modified autofs code to communicate the server export details from automount daemon to kernel, in smaller chunks and thus avoiding the hang.
Temporary fix
