Problem Native export - HTTP 500

Software Support
1

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:
https://support.plesk.com/hc/en-us/articles/213399589-Websites-are-slow-and-a-warning-appears-in-logs-mod-fcgid-ap-pass-brigade-failed

Does increasing the FcgidMaxRequestsPerProcess value resolve this?

3

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

4

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?

5

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
