The Cb Response Server is unable to accept binaries from sensors since it is unable to write to its working directory /var/cb/nginx/client_temp. Sensors continue to attempt to upload the binary to the server causing network bandwidth problems. This can occur after a server move where permissions were not correctly copied over.
- Stop cluster:
|/usr/share/cb/cbcluster stop |
- Check for hanging processes:
- Move client_temp so that nginx would regenerate the directory:
|mv /var/cb/nginx/client_temp /var/cb/nginx/client_temp_old |
- Start cluster:
|/usr/share/cb/cbcluster start |
- Verify that minions are receiving 200's for storefile submits:
|tail -f /var/log/cb/nginx/access.log |
