Took 3 different datadumps from my production forum today and tried importing them to my local sever copy and the import just dies, no errors. Dies in different places bu generally in this area:

Process table fud30_level:
...4 rows loaded.
Process table fud30_mime:
...43 rows loaded.
Process table fud30_mod:
...6 rows loaded.
Process table fud30_msg:

From the apache error log:

[Fri Jan 09 16:44:59.256328 2015] [:error] [pid 3267] [client 127.0.0.1:45795] PHP Warning:  Error while sending QUERY packet. PID=3267 in /home/curvex/public_html/FUDforum/include/theme/default/db.inc on line 110, referer: http://127.0.0.1/~curvex/vgforum/adm/admimport.php?&SQ=d510e0c9a990849a48d0e9e2b354f38d
[Fri Jan 09 16:45:00.174981 2015] [core:notice] [pid 588] AH00052: child pid 3267 exit signal Segmentation fault (11)

Interesting to know that I went back to a last year datadump, 11/29, after the upgrade to 3.0.6 and this datadump imports without issue. Did this import 2 times and both successfull. Also successfully (by mistake) imported a 3.0.5 backup onto a 3.0.6 release. Actually works.

Note after the import dies the forum is inaccessable. You have to run a fresh installl of the forum.

I'm not sure what's gpoing on, any help would be greatful.
Thanks!

Have you checked for errors in your web server's error_log?

Yes the above code snippet is from my server's http error_log. I suspect that I'm hitting a size limit, memory, ect...Successfull imports are 510mb compressed. The imports that die are 550mb.

Might be time execution limit: I don't quite remember how it is handled, but the runtime might just kill the process unceremoniously.

Bypassed the webserver and tried importing the lastest backup via the command line using php -q adminimport.php command. Got the same error but with more output and corefile dump:

Process table fud30_mod:

Good news! The max_allowed_packet from the core dump quizzed me to do a goggle search and found this to be a mysql setting. Suggestion was to change/add the setting max_allowed_packet=256M to the my.cnf file. I had to add this line in.

Import worked! Should add this workaround to the documentation. I assume most hosting providers have this packet allocation set. Unsure of what the default is by not having this specified.

I'm just glad now that I can verify my backups.
