Alerts problem on 6.1.1

[macewindum]

Since I upgraded SPLUNK to 6.1, I have a problem with my alerts.
After few hours they stop working. I must restart SPLUNK and my alerts are back to work until they stop working.
How can I resolve that ?

Ran into this over the weekend myself. It looks to be known issue SPL-84357

The response I found at
http://answers.splunk.com/answers/137421/why-are-my-real-time-alerting-searches-no-longer-sending-em...
provided the following workaround:

The work-around is to temporarily extend "sessionTimeout" in $SPLUNK_HOME/etc/system/local/server.conf to a value that will be longer than the interval between two matched events, thus preventing the token from expiring:
[general]
sessionTimeout = 30d

Thanks for the answer.
