Hi, Andrew.

Well, not so fast I guess.  It just happened again on Saturday, this
time using NFSv2 (using the image you sent me).  The error messages on
the console look the same:

=== console ===
save_restore:write_it: fprintf returned -1. [131101-194540]
../save_restore.c(1636): [0x2f0003]=write_it:S_rpcLib_RPC_CANTSEND
save_restore:write_it: fclose('auto_settings.sav') returned -1
../save_restore.c(1751): [0x2f0003]=write_it:S_rpcLib_RPC_CANTSEND
save_restore:write_it: Giving up on this attempt to write 'auto_settings.sav'. [131101-194540]
===============

This is driving me nuts.  Without a fix for this, I'm going to have to
start rebooting this IOC once a week to try to keep it from happening.
I'd strongly prefer not to have to do this.  Any ideas on how to
investigate, fix, or work around?

The software running on the IOC has changed a bit since I first reported
this problem; it is now running 3.14.12.3 (+ Known Problems patches) and
synApps 5_6 with autosave 5-1 (+ many other module updates).

Thanks,

Lewis
