вот проблема:
Моя задача - управлять синхронизацией БД через SOAP (пожалуйста, не спрашивайте меня, почему, мне только что сказали сделать это именно так), и я получаю непостоянную ошибку при передаче данных. Он может появиться после того, как пройдено 500 записей, может появиться после 20000, может даже не появиться вообще, поэтому я предполагаю, что это не поврежденные данные в БД.
Журнал этой ошибки:

Я использовал URLEncode / URLDecode и принудительно использовал UTF-8 для передаваемых данных, как это было предложено в аналогичном вопросе SO с этой проблемой с недопустимым символом - это не помогло.
Также есть еще одна ошибка, которая случается очень редко:
