从bottle.py中恢复错误:[Errno 32]管道破裂

Question

我有一个小的WebApp,它由一个小表单组成,用户必须输入一些凭据,并将其发布到我的瓶子应用程序.输入得到验证(通过一堆sql调用),如果一切正常,他会收到一封邮件.问题是:运行服务器后一切都很好单元我得到这样的错误:

Traceback (most recent call last):   File "/usr/local/lib/python2.7/SocketServer.py", line 295, in
_handle_request_noblock
    self.process_request(request, client_address)   File "/usr/local/lib/python2.7/SocketServer.py", line 321, in process_request
    self.finish_request(request, client_address)   File "/usr/local/lib/python2.7/SocketServer.py", line 334, in finish_request
    self.RequestHandlerClass(request, client_address, self)   File "/usr/local/lib/python2.7/SocketServer.py", line 651, in __init__
    self.finish()   File "/usr/local/lib/python2.7/SocketServer.py", line 710, in finish
    self.wfile.close()   File "/usr/local/lib/python2.7/socket.py", line 279, in close
    self.flush()   File "/usr/local/lib/python2.7/socket.py", line 303, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size]) 
    error: [Errno 32] Broken pipe

我GET和POST侧面的功能看起来像这样:

@get("/myroute")
def show_form():
    form = CreateVoucherForm()
    return generate_form(form)

@post("/myroute")
def validate_storno():
    formdict = dict(request.forms)
    form = CreateVoucherForm(**formdict)
    if form.validate() and has_no_logic_errors(form):
        #query some SQL
        #send the user mail and give him the same form with success msg
        mail(form)
        return generate_form(form, "Success")
    else:
        #return form and deny msg
        return generate_form(form, "Access Denied!")

我已经在SO阅读了这些主题:

• 捕获瓶子服务器错误
• 如何对追赶错误号-32破碎管中A-WSGI处理程序
• 用瓶的框架,打破管错误蟒蛇粘贴 -

但是给定的解决方案(如果有的话)在我的情况下不起作用.唯一似乎有帮助的是重启服务器.在那之后,一切都会再次运作,直到下一个小时.

有可能从这种情况中恢复过来吗？

我不想每小时安装一个cronjob重新启动我的服务器,这太可疑了.如果您建议使用其他服务器,它应该像瓶子一样容易使用.我也不想使用像django这样的完整框架,因为它很重要.
