Well, as the subject says, fstab: /etc/fstab:0: Too many open files

An error message displayed from nextcloudclient started from command line.

14.0-STABLE
nextcloudclient-3.12.2
xfce4
kern.maxfiles: 25132743
kern.maxfilesperproc: 7539822
ZFS filesystem version: 5
kern.openfiles: 79866
p1003_1b.mapped_files: 200112
compat.linux.default_openfiles: 1024

Actual number of files in that particular file system are 92538

Can someone please give an explanation to the somewhat cryptic error 
message?

Thanks,

Per
