I have a production Java application hosted on Jetty. During the last week or so, the system has crashed, leaving only a single message accessed with "dmesg":

java[20551]: segfault at 000000004315dd78 rip 00002aae428a018d rsp 000000004315dd60 error 6

Can anyone point me in the correct direction as to what this means ?

Are your javacand java the same version? This is usually the problem when you get this error.

You can get the versions like this: which -a java and which -a javac
