Symptoms

Cannot access file manager. CCP throws the error:

Internal error: Connection to the agent at '' failed.
Message     Connection to the agent at '' failed.
File    JsonRpc.php
Line    240
Type    Service_Agent_Exception

The following output can be found in the /opt/psa_agent/logs/agent.log file:

2015-07-21 10:42:20 [AGENT][ERROR]: Unable to makeDir /opt/psa_agent/tmp/500c89ac7284bd3cddd1def386dcbf95. Error occured: boost::filesystem::create_directory: No space left on device: "/opt/psa_agent/tmp/500c89ac7284bd3cddd1def386dcbf95"

2015-07-21 10:42:20 [AGENT][ERROR]: [AGENT][SYSTEM ERROR]: Unable to makeDir /opt/psa_agent/tmp/500c89ac7284bd3cddd1def386dcbf95. Error occured: boost::filesystem::create_directory: No space left on device: "/opt/psa_agent/tmp/500c89ac7284bd3cddd1def386dcbf95"

Cause

The service node the websites hosts on runs out of diskspace:

# df -h
Filesystem                       Size  Used Avail Use% Mounted on
/dev/mapper/vg_web01-lv_root     99G   94G     0 100% /

Either the case might be about the lack of inodes:

# df -i
Filesystem                      Inodes   IUsed   IFree IUse% Mounted on
/dev/mapper/vg_web01-lv_root    655360  655360       0  100% /
/dev/root                       655360  655360       0  100% /

Resolution

Refer to your system administrator to increase the amount of diskspace / inodes.
