Problem Native export - HTTP 500

Hi everybody,
I have to export metadata from ojs 3.1.1.4 to OJS 3.1.1.4 .
But half of the numbers are ok, but half appears with HTTP 500. Can you help me - where is the problem.
Maybe in which tables should I check empty fields locale or setting_value that can validate and fix this error (half exports correctly)

Unless there is another line referencing “PHP Error” or “PHP Fatal”, the only line above which could cause a HTTP 500 error is:

[Tue Dec 11 21:25:11.311490 2018] [fcgid:warn] [pid 23714:tid 140631478185728] (32)Broken pipe: [client 85.221.208.178:50685] mod_fcgid: ap_pass_brigade failed in handle_request_ipc function, referer: http://libcom2.ayz.pl/erfin/index.php/BibAnn/management/importexport/plugin/NativeImportExportPlugin

A web search for this error yeilds:

Does increasing the FcgidMaxRequestsPerProcess value resolve this?

I checked, but I have 500,000 set.
Other suggestions?

Can you confirm whether this message occurs each time the export fails?

Or, is there any other “PHP Error” or “PHP Fatal” message at the time of the failure?

I made the test one more time. Please, look at attachements
http://libcom2.ayz.pl/log_export.txt

and encore

Bingo. Increase your available memory for PHP, or select a smaller subset in the export to limit the size.

Yes, It works :slight_smile:Thanks
