Should I be worried about these error messages?

[Alex Sharaz]

I'm seeing a fair number of error messages of the form
 Error: Couldn't open
/var/cache/freeradius/tlscache/e60f73c400b6462028a381a46f584d59f25f392c59d217981221a60eba9b3345.vps
for reading: No such file or directory

on our 3.0.12 servers with eap caching enabled.Would you see this if the
cache entry has expired or is it something else?
