getaddrinfo() thread failed to start during long CSV import

[Ekaterina Galiakhmetova]

Hi all,

I’m having a problem with long CSV imports using csv:import. After about 15 minutes, the import fails and I see this error repeated many times:

.getaddrinfo() thread failed to start
PHP Fatal error: require(): Failed opening required …

Before that, everything works fine.

On my server:

• RAM: 15 GiB

• Swap: 2 GiB

Not sure if this is a known issue. Any advice would be really appreciated.

Thanks!

Hi Ekaterina,

Could you provide an idea of how many lines your CSV file is, the full command you used to try the import, and the version of AtoM you're using? Also, if there are any additional details regarding the error messages you're getting, that would be helpful. I'm curious to see if this can be replicated reliably or if it's something to do with your environment specifically; if I can replicate it it should be possible to provide a fix in future versions of AtoM.

Best,

-Daniel

Hi Daniel,

We're using AtoM 2.7.1.

The CSV had around 1000 rows. But I noticed something interesting: 
If there are no digitalObjectURL values (links to digital objects stored in our AWS S3), the import works fine even with 3000+ records. 
If digitalObjectURL is present, errors start happening once there are ~500+ records (after ~15 minutes). 

Here's the error log:

PHP Fatal error:  require(): Failed opening required '/usr/share/nginx/atom/vendor/symfony/lib/exception/sfDatabaseException.class.php' (include_path='/usr/share/nginx/atom:/usr/share/nginx/atom/vendor/symfony/lib/plugins/sfPropelPlugin/lib/vendor:/usr/share/nginx/atom/vendor/symfony/lib/plugins/sfPropelPlugin/lib/task:/usr/share/php') in /usr/share/nginx/atom/vendor/symfony/lib/autoload/sfCoreAutoload.class.php on line 100

Full command I used: 

sudo -u www-data /usr/bin/php -d memory_limit=-1 /usr/share/nginx/atom/symfony csv:import /home/deploy/csv-files-archival-descriptions/2026-02-09.csv

Let me know if you need anything else. 

Thank you!

Best, 
Ekaterina
