Hi,

  When we tried to use the synApps-autosave in a PowerPC VxWorks IOC (base 3.15.4 / autosaveR 5-7-1), There were a lot of error?/Annoying messages appear periodically. But the autosave was able to work properly.
  The NFS configuration is :" /home/long/ntfDir *(insecure,rw,sync,no_root_squash)".
  We also checked the IOC and the nfs server time, there were no problems.

Here is the report:
