Permintaan RPC amqp musim semi ke Rabbitmq mendapatkan batas waktu

Saya menggunakan fungsi AmqpTemplate.sendAndReceive dari beberapa server, ini berfungsi dan koneksi ulang berfungsi setelah Rabbitmq dimulai ulang atau masalah jaringan.

Ini bekerja dengan baik selama beberapa minggu tetapi tiba-tiba salah satu server saya mendapatkan waktu tunggu untuk setiap panggilan sendAndReceive, kelincimq menerima pesan dan sedang diproses tetapi sendAndReceive tidak mendapatkan respons (batas waktu balasan disetel ke 60 detik dan itu hanya membutuhkan beberapa detik untuk memproses pesan). Server lain bekerja pada waktu yang sama dengan kode yang sama dan menggunakan antrian yang sama.

Server kembali berfungsi hanya setelah saya memulai ulang layanannya.

Saya rasa ini ada masalah penyambungan ulang (walaupun pesan berhasil dikirim ke kelincimq), mungkin pendengar respons AmqpTemplate tidak menyambung kembali atau semacamnya.

Adakah yang tahu apa masalahnya? dan bagaimana saya bisa mencegah hal itu terjadi lagi?

pengaturan ConnectionFactory saya:

setConnectionTimeout(1000);
setRequestedHeartbeat(100);
setTopologyRecoveryEnabled(true);
setAutomaticRecoveryEnabled(true);

Sunting:

Versi pegas-AMQP: 1.4.3

<bean id="myConnectionFactory" class="path.to.myConnectionFactoryClass"></bean>

<rabbit:connection-factory id="myRabbitConnectionFactory" connection-factory="myConnectionFactory" channel-cache-size="25" />

<rabbit:template id="myTemplate" connection-factory="myRabbitConnectionFactory" reply-timeout="65000" />

Sunting:

Itu terjadi lagi, saya melihatnya berhenti berfungsi setelah saya mendapatkan kesalahan:

Tidak yakin mengapa sambungan ditutup dan mengapa tidak tersambung kembali.
