[Koha] Help testing marc staging performance issues

[Barton Chittenden]

Hi, All!

At ByWater, we've had a few reports of

"Home › Tools › Stage MARC records for import" timing out on large import
batches, with the message "there was an error."

When this happens, there are typically two batches under

Home › Tools › Manage staged MARC records

The first batch will show a number of records, and the second batch will
show 0 records.

I believe this typically happens under plack. I'm having a *very* difficult
time re-creating the error, so I don't have any plack error logs, I don't
have any good numbers on how many records cause the problem.

One of our libraries told me that the problem seems to be worse when using
matching rules.

If you've seen issues like this, I would love to know

1) What version of Koha you're using
2) How many records you were importing
3) If you were doing any sort of record matching
4) Any other relevant details
5) If you have access to the server error logs, I'd like to know what
messages you see there.

I'd like to file a bug, but without being able to replicate the problem, I
can't get any traction there.

Thanks,

--Barton
