PHP dropped the connection. By chance is PHP_FCGI_MAX_REQUESTS set somewhere for the PHP process? In the old days it defaulted to 500 (exit after 500 requests), which led to exactly this scenario, but with php-fpm it defaults to 0 (don't exit). > > Is it possible that somehow php processed the begining of the aborted > POST truncating the data in the database ? > Unclear...
