NFS v4 and SQlite3 databases
I got a problem as I attempt to configure a new Sun Ray Server on Solaris Oracle Solaris 11.1.21.4.1 where the user home directories are provided via NFS (also Solaris11).
All works good until I start firefox 31esr. Than the whole system got very slow, the NFS device is 100% bussy (shown on NFS Client) and the are latencies over 10sec. The NFS server show no significant load.
nfswizard.d shows me that there a lot of slite3 db are opened by firefox. A short googleing shows also that it is not recommended to put sqlite3 DB's on NFS servers, especaily on NFS v4. But use of NFS v3 makes it a little bit better, but the problem still persist.
