Anshul Gangwar commented on CLOUDSTACK-1863:
--------------------------------------------
Problem seems to be with your log4j configuration file. I am not sure about the
case when the code is working fine but you are getting
java.lang.ClassNotFoundException:
org.apache.cloudstack.alert.snmp.SnmpTrapAppender in logs. If the
ClassNotFoundException is there then code should also not work. But that is
working fine. Try creating new setup and then check for this exception.
Probably your log4j is in inconsistent state after you added confusing loggers.
