Cannot clear table &1

What causes this issue?

Table &V1& contains invalid entries and cannot be cleared at this time.
This situation can only happen if some data was stored in table &V1&
after the start of the job. Extraction jobs always clear table &V1&
at the beginning of the run. However, during the processing of a
particular segment, table &V1& cannot be cleared for technical
reasons.

System Response

Processing continues, but application server memory is used instead of
table TXW_INDEX. This may lead to memory shortages at a later time
during this job.

How to fix this error?

There is no particular action necessary. If the job fails, then
restarting the job should clear table &V1& .
