문자열이 web.conf에서 시간 제한 값 중 하나로 설정되었는지 확인합니다.

$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

위의 설정은 기본 설정이지만, 문자열이 문자열(예: tools.sessions.timeout = 1h)로 변경된 경우 기본값으로 되돌리고 문제가 지속되는지 확인합니다.

해결

모든 시간 초과 값이 유효한 경우 가능한 해결 방법은 max-age를 명시적으로 설정하기 위해 sessions.py를 수정하는 것입니다.
 

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

다음을 변경합니다.
 

# 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)

변경 후 명령문:

# 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'] = 86400
###   if timeout:

그런 다음 Splunk를 다시 시작합니다.
