[OpenSIPS-Users] Restart_persistency .cache permissions

[Răzvan Crainea]

Hi, Alex!

OpenSIPS tries to write the file in the working directory, that is by 
default the home of the running user, opensips. Apparently he's not 
allowed to create the file there. You have 3 solutions:
1. make the working directory writable
2. specify a new work directory (using the -w parameter)
3. Specify a full path for the restart_persistency_cache_file[1]
