python - Django AdminEmailHandler causing wsgi to hang -

i'm building webapp using django 1.7 on python 2.7, deployed in production apache , mod_wsgi in daemon mode. i'm having problem wsgi hangs whenever have exception logged (with python logging) , adminemailhandler configured in settings.py.

when request page browser hangs until apache log shows "end of script output before headers: wsgi.py"

i have 2 logging handlers configured, filehandler , adminemailhandler, , when comment out adminemailhandler problem doesn't occur.

'handlers': { 'file': { 'level': 'info', 'class': 'logging.filehandler', 'filename': '/var/log/apache2/mylog', 'formatter':'simple', }, 'email': { 'level': 'error', 'class': 'django.utils.log.adminemailhandler', 'formatter':'simple', }

i have seen configure wsgi with

wsgiapplicationgroup %{global}

and there application issues mod_wsgi (from this question).

however maintain daemon mode if possible, , adminemailhandler seems core piece of logging functionality i'm surprised hasn't been encountered before!

thanks in advance help

update

i fixed issue own subclass of adminemailhandler delegates email sending separate thread. vinay help!

from threading import thread import django.utils.log djangolog class myadminemailhandler(djangolog.adminemailhandler): def emit(self, record): try: thread = thread(target=djangolog.adminemailhandler.emit, args=(self, record)) thread.start() except: self.handleerror(record)

i don't believe related daemon mode - it's more smtp blocking web app. see this question , answers possible solution.

python django apache logging wsgi
