It's possibly MAGNOLIA-2032 [1] - can't you update to at least 3.5.4, .
8 would be better, 3.6.1 even more ?

Hi All
I investigated some more and checked the line mentioned in the NPE
stacktrace:
It seems to be caused by call to the object returned by
IPSecurityManager.Factory.getInstance(), which means that the
getInstance method returns a null reference.
Can anyone think of situations where this could happen?
cheers

Betreff: [magnolia-user] Nullpointer when restarting Magnolia
Hi List
I am running two Magnolia Webs on Magnolia 3.5.2/Tomcat/mysql and
experience strange behaviour from time to time when restarting tomcat:
First, everything seems to be normal, I can log into the author
instances and work. However after a couple of hours, sometimes days,
the author instances stopp working.
Tomcat displays the following error message instead of the magnolia
login:
HTTP Status 500
java.lang.NullPointerException

I get these quite regularly, and sometimes have to restart like 5
times until it doesn't happen again. This makes installing updates
on the server that involve restarts quite painful.
Did anyone experience the same or has an idea how to fix this?
Cheers
Claudio
