Question:
I'm receiving the following error whenever the Centova Cast cron job runs:Unable to create lock file: Permission deniedHow do I fix this?
Failed to start up concurrent users module!
Answer:
This error is actually generated by PHP, not Centova Cast, and has nothing to do with Centova Cast itself.The nature of the problem will depend on the exact error message shown after "Unable to create lock file:", however if you see "Permission denied" as shown above, it's likely that your /tmp/ directory is not writable.
Running the following commands should fix it:
chmod 0777 /tmp
chmod +t /tmp
