Error Code

S01026

Error Message

CacheDumpTaskDispatcher::<function> <action>. Out of memory error occurred while <desc>. Will retry in <retryInterval> seconds. RefId:S01026

Probable Causes

CacheDumpTaskDispatcher periodically flushes the data cached in TSDB to disk. This process may cause an out-of-memory (OOM) error, and this error is reported. CacheDumpTaskDispatcher will retry after a certain interval. This operation will keep retrying until the TSDB flush operation is completed.

In the error message:

function: the executed function.
action: the action CacheDumpTaskDispatcher is executing.
desc: the action description.
retryInterval: the retry interval, usually 1 second.

Solutions

Check if null values are contained in the partitioning column.
