I'm using Feeds to migrate from wordpress using the WXR. I'm using the last Feeds, Feeds XPath Parser, Feeds Tamper, Media and Media Feeds.

No more errors in logs or in the screen.

About 80% of the content is imported...maybe there are some content with something unespected? If i load the WXR in my browser hasn't any XML errors.

If i split the WXR in several files, for example one for each author then the import process works well without any error.

¿Maybe it's only with large files?

I've changed some php setings.
php_value max_execution_time 3000
php_value max_input_time 6000
php_value upload_max_filesize 50M
php_value post_max_size 50M
php_value memory_limit 256M

Oddly, I'm having a similar Batch API problem importing WordPress WXR fields using migrate and wordpress_migrate: #1600710: Batch API failures when continuing a migration. It works fine with Javascript disabled, or doing the import from drush, so it's nothing so simple as the WXR throwing errors. Maybe something with the PHP XML extensions not cleaning up properly?

Check your error log for PHP Fatal errors, I've experienced such a problem in #1660950: FeedsSource expects stored $state to be array, which is not always the case

After partial installation, I get the error:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: StatusText: Internal Server Error ResponseText:

and when I click on the error page I get:

Failure to sort migration list - most likely due to circular dependencies involving CommerceKickstartNodebags_cases,CommerceKickstartNodedrinks,CommerceKickstartNodehats,CommerceK

I tried to re-install, then got the same first error, then the white screen of death...

not sure what to do from here?

@gilmorelou, sorry, but your error has nothing to do with Feeds, which the issue is in. Please look for a similiar issue on either Commerce Kickstart or Drupal.

Not sure this will help. I have experimented a similar error message An AJAX HTTP request terminated abnormally. Debugging information follows. Path: /batch?id=12&op=do StatusText: ResponseText: Re with the difference of the id of the batch.
It occurs while I was importing the french translations of Drupal core, Chaos tools, Internationalization, Localization updates, Pathauto, Token, Transliteration, Variable, Views (and Views translation which failed cause it hasn't translations yet) in this page : admin/config/regional/translate/update.

After completing 4 of the 24 importation files, it occurs, but one the module translation importation was a success. So then I gave 2 other tries, and step by step the whole importation was done succesfully.

So my idea is that it might be related to the size of the importation or the duration caused by the size.

Sorry if this was not useful.

#7: Have you checked web server error logs? If script unexpectedly fails, that's the first place to look at

#8 : Is it the log messages in the reports of the Admin interface? (sorry if my question seems stupid, I am a newbie)
In that case there is currently nothing about this issue. Nor in the watchdog table in the database.

I just checked my web host and it seems that I can access to some logs online. Thank you for this info, I'm discovering. I just tried and it doesn't work for the concerned website.
I'll try again later and give you infos if there is anything relevant if you think it is useful?

The same like in #7.

By the way, is looking it begins to happen after install module httprl (

Something related to http requests synchronization?

#11 was spot on. I disabled HTTPRL and then updates began to work again.
