Opened: Sep 20, 2019

Severity: 2-Critical


The /var partition might become completely full on the disk due to tmp files being written to /var/config/rest. This condition may be accompanied by console error messages similar to the following: 011d0004:3: Disk partition /var (slot #) has only 0% free on secondary blade. Additionally, there may be periodic restjavad and bigd daemon restarts related to disk space exhaustion.


The partition housing /var/config/rest may become 100% full, impacting future disk IO to the partition.


Process traffic while DoS Dashboard is open. This issue is happening because a VIPRION process is not available because of a REST timeout.


Manually run the following commands, in sequence: bigstart stop restjavad rm -rf /var/config/rest/*.tmp bigstart start restjavad

Fix Information

Increased the rest socket timeout value and shellexecutor timeout value to 6 min to fix the timeout issue of viprion worker ?The fix also includes automatic removal of unused tmp files.
