Controleer of een tekenreeks is ingesteld als een van de time-outwaarden in web.conf

$SPLUNK_HOME/bin/splunk btool web list settings

[settings]
busyKeepAliveIdleTimeout = 12
keepAliveIdleTimeout = 7200
response.timeout = 7200
splunkdConnectionTimeout = 30
tools.sessions.timeout = 60
ui_inactivity_timeout = 60

Bovenstaande zijn de standaardinstellingen, maar als er een string is gewijzigd (bijvoorbeeld tools.sessions.timeout = 1h), keer dan terug naar de standaard en controleer of het probleem zich blijft voordoen.

resolutie

Als alle time-outwaarden geldig zijn, is een mogelijke oplossing om session.py aan te passen om de maximale leeftijd expliciet in te stellen.
 

$SPLUNK_HOME/lib/python2.7/site-packages/cherrypy/lib/sessions.py

Wijzig het volgende:
 

# We'd like to use the "max-age" param as indicated in
    # http://www.faqs.org/rfcs/rfc2109.html but IE doesn't
    # save it to disk and the session is lost if people close
    # the browser. So we have to use the old "expires" ... sigh ...
##    cookie[name]['max-age'] = timeout * 60
    if timeout:
        #cookie[name]['expires'] = http.HTTPDate(time.time() + (timeout * 60))
        # Replace Cherrypy's version of this so that cookies alwasy last for
        # 24 hours by default - Setting them to 1 hour causes problems for IE
        # users who's clocks are off from the server
        timeout = timeout * 60 # convert to seconds
        if timeout < 86400:
            timeout = 86400 # Cookies last at least 24 hours
        try:
                cookie[name]['expires'] = http.HTTPDate(time.time() + timeout)
        except TypeError:
                raise AssertionError("HTTPDate error, timeout=%s not set." % timeout)

Op deze:
 

# http://www.faqs.org/rfcs/rfc2109.html but IE doesn't 
# save it to disk and the session is lost if people close 
# the browser. So we have to use the old "expires" ... sigh ... 
## cookie[name]['max-age'] = timeout * 60 
cookie[name]['max-age'] = 86400
###   if timeout:

        # Replace Cherrypy's version of this so that cookies alwasy last for
