Hi everybody mi Name is Aldo, and I have a really bad problem since a couple of months. I got a farm with several jboss servers. Sometimes I can see them alerted, through the JON console, with not apparently reason. I checked amount of memory and processor but both of them are ok.

Then I tried to access to those jboss through admin_console but I got a message of

log in attempt failed, please try again

What I did next was execute a twiddle.sh command like

./twiddle.sh --server=jnp://10.0.41.139:1099 --user=admin --password=XXXXXX query *:*

15:08:09,396 ERROR [Twiddle] Exec failed

java.lang.SecurityException: Failed to authenticate principal=admin, securityDomain=jmx-console
