[Freeswitch-users] ERROR! unable to open ZRTP cache file

[Steven Ayre]

It's a log message from within the libzrtp library.

It means it cannot open the cache file. The log message contains the
filename it tried to open, but it looks like you've removed the end of
the lines with that information.
The default filename within the library is
"./zrtp_def_cache_path.dat". That'd be within the cwd FS is running
with, which you can find with "ls -ld /proc/PID/cwd" where PID is the
PID freeswitch is running as.

The most likely cause is perhaps a write permission error. libzrtp
doesn't log the error that occurred, but you might be able to see it
by attaching strace, but it'd first be easier to check if FS can write
to its cwd directory.
