Dropping high-priority samples from GCFSampleStore: no thrown errorDescriptionSystem logs start showing error: high-priority samples from GCFSampleStore CauseThis is caused by the GCF Sample store sample queue growing too large on the node. There is a sys_trigger job called: Drain GCF Sample Queue There is a number of these jobs on the instance. The parent for All nodes, and then a job per node on your instance. In some cases, there is not a job for that given node and it will cause the sample queue to grow and never be removed. ResolutionIf you do not see a job for each node in your instance do the following: 1) Run the Drain GCF Sample Queue job which has system ID = ALL Nodes This will generate a job for each node and will clear out the sample queue and solve this issue.
