如何解决新安装的Magento 2.3.4后24小时清漆显示503错误
我遇到“错误503服务不可用”的问题，24小时后显示错误。我正在使用varnish-6.5.1使用最新的nginx服务器进行全页缓存。 Magento版本是2.3.4。我正在使用SSL证书，Magento处于开发人员模式。 我的清漆配置如下：
sudo systemctl edit --full varnish
[Unit]
Description=Varnish Cache,a high-performance HTTP accelerator
After=network-online.target nss-lookup.target
[Service]
Type=forking
KillMode=process
# Maximum number of open files (for ulimit -n)
LimitNOFILE=131072
# Locked shared memory - should suffice to lock the shared memory log
# (varnishd -l argument)
# Default log size is 80MB vsl + 1M vsm + header -> 82MB
# unit is bytes
LimitMEMLOCK=85983232
# Enable this to avoid "fork failed" on reload.

# Maximum size of the corefile.

如何检查导致错误的原因？
解决方法
我使用命令
sudo varnishlog -d -q "vxid == 557088"
错误是“重启次数过多”，下面我粘贴了完整日志

我将此代码添加到了我的default.vcl文件中：
import httpx
import asynctest
import pytest
class DebugClass:
async def post(self):
try:
async with httpx.AsyncClient() as client:
res = await client.post(url='http://localhost:8080',data=test_data)
return "OK"
except Exception as e:
return "NOK"
@pytest.mark.asyncio
async def test_debug_class_post():
with asynctest.patch('httpx.AsyncClient.post') as post_mock:
post_mock.side_effect = TimeoutError
debug_class = DebugClass()
res = await debug_class.post()
assert res == "NOK"
它似乎可以正常工作，目前没有503错误。
