为了集成我们的 Mercurial 存储库和我们的错误跟踪器（Bugzilla 4.0.1），我设置了服务器端hgrc文件，如下所示：
[extensions]
hgext.bugzilla=
[hooks]
incoming.bugzilla=python:hgext.bugzilla.hook
[bugzilla]
bzurl=http://localhost/bugzilla
user=some.user@this.domain
password=password
version=xmlrpc
hgweb=http://this-server:65432/
template=Changeset {node|short} in {root|basename}.\nDetails siehe {hgweb}{webroot}?cmd=changeset;node={node|short}\nBeschreibung:\n\t{desc|tabindent}
[usermap]
committer_email=bugzilla_user_name
[web]
push_ssl=False
allow_push=*
baseurl=http://this-server:65432
Mercurial 设置为在this-server的端口65432上提供服务。
现在，在开始之后hg serve，第一次推送将被处理得很好。在提交消息中发现的所有错误引用都将生成 Bugzilla 注释。但是在每次出现至少一个错误引用的后续推送中，都会向用户显示以下错误消息：
pushing to http://this-server:65432/
searching for changes
remote: adding changesets
remote: adding manifests
remote: adding file changes
remote: added 1 changesets with 1 changes to 1 files
remote: error: incoming.bugzilla hook failed: Bugzilla error:
曾多次观察到此消息：
remote: error: incoming.bugzilla hook failed: Bugzilla error: [Errno 54] Connection reset by peer
在 bugzilla 中不创建任何评论。重新启动hg将使其再次正常工作。
我还尝试使用参数启动 Mercurial 服务器，-A ... -E ...以使其创建访问和错误日志。访问日志显示每个请求的相同类型的交互，无论成功与否：

错误日志为空。
如何进一步诊断此问题？
