## Profiler: New session rejected
|
|
|
|
|
|
|
|
|
|
If you see the following error when computing the profiler `New session rejected due to limit, already XYZ sessions active`,
|
|
|
|
|
it means that the number of threads configured in the profiler workflow is exceeding the connection limits of your
|
|
|
|
|
Vertica instance.
|
|
|
|
|
|
|
|
|
|
Note that by default the profiler runs with 5 threads. In case you see this error, you might need to reduce this number.
