Trying to import my (rather large, 2Mb flatfile) MT blog. Get this error message (yuck):

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 89 bytes) in /home/swissblogs/www/blog/wp-admin/import-mt.php on line 66

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 21 bytes) in Unknown on line 0

You might want to try splitting the file into file sof sixe < ~800Kb and importing the entries. The size restriction and the memory restriction is due to your server, and this problem has be recorded on the support forums before.

Does your server happen to be running FreeBSD?

I've been able to reproduce the above problem when attempting to import an MT-exported blog on a FreeBSD server. But as I discovered at <a href="">this support thread</a>, the problem seems to be with FreeBSD and PHP. Namely, to resolve this, you have to edit php.ini and temporarily change this line:

memory_limit = 8M ; Maximum amount of memory a script may consume (8MB)


memory_limit = 128M ; Maximum amount of memory a script may consume (8MB)

Also, on a later import, when I forgot to change that setting, I didn't get the "Fatal error" message mentioned above; I just got a blank page.

Not sure when this error gets triggered by a certain sized import file, or if it is always the case for an import under FreeBSD. For reference, the two blogs I imported were 1.2 and 1.6 MB import.txt files.

Ah, <a href="">here's</a> another support thread with more people addressing the issue. There another suggestion is to split up the import file into <800kb chunks and import them separately.

  • Owner changed from anonymous to matt
  • Resolution changed from 10 to 70
  • Status changed from new to closed

That's a host issue, basically saying that it ran of memory while processing the import. Try breaking up the file into two or there smaller files.
