Crash of metadata-import into workflow

[Marwa Saada]

Hello dspace team,

We had a problem with metadata import after switching to dspace 7, on the productive server the import only works if the Excel file has a certain number of items (was 8) otherwise the process craches and no items will end up in the workflow, also there is no error message or clear exception.

With debugging we found that the process stops in the EventServiceImpl class, and when we increased the values of pool configuration keys ( maxTotalPerKey, maxIdlePerKey, maxTotal ) there, the import continued successfully with a file up to 25 items.

Are there any consequences that these keys have other values than the one already initialized in Dspace (100, 5, 100).

I would appreciate an explanation
