[Bug]: The "kernel" service is synthetic error when processing parallel

[IronSean]

Expected behavior

datahub:data-importer:process-queue-parallel will properly process rows, or throw errors when there is a logic error

Actual behavior

Occasionally rows fail with the following error:
Error processing element: IMPORT,DATA,HERE The "kernel" service is synthetic, it needs to be set at boot time before it can be used.

This seems like a possible race condition as it seems to happen more when the server is under load by other tasks, but I might be imagining that.

Steps to reproduce

Inconsistent. Run lots of 10k, 100k, 1m row datahub imports with multiple parallel workers (8 in my case on 4 cores) while the server is under other workloads.

Sometimes there is no error, sometimes a few rows, and sometimes the whole import fails.

Hi everyone,

is there something new in this? I also occur this error since a few days?

we are not able to reproduce it, see also thread here, which is a similar topic.
any additional insights or debugging results are welcome.

@stephangmms it's happening when importing a large number of products with a large number of attributes we had more than 200+ attributes for each product.

that sounds familiar. Sadly i have not too much insight into that problem because i was out of this project for a while. I only know that the data-importer jobs (csv-imports, parallel execution) run in small scale test (<100 items) perfectly. Now as we are testing 5000+ products with only 3 attributes/product this problems occur.
