WebLogic admin server not starting.

Question

Hi all,
I have a problem with my WebLogic Admin server not starting. Following a VM reboot last week our admin servers are no longer starting. On this particular server we have 3 admin servers serving 3 separate environments.
Theserver seems to be getting stuck right at the very start. I have tried removing tmp, cache and ldap directories. Searched for and removed all .lok files. I have manually turned on full debug to try and flush some extra information through standard out but no luck. It is very peculiar. When we have exported the domain to another box and started the admin server it has come up successfully.
This is the output from the logs - this is literally as far as it get before it hangs and does nothing. As far as I know the next thing WebLogic is doing is checking the version. Has anyone any ideas what the problem could be? It is server wide as all 3 admin servers on the same box are suffering the same problem.
This is Weblogic 10.3.2 on a Solaris vm

Answer 1

Just a wild guess (as you have restarted the physical servers), it could be related to the entropy of the machine.
What you can try to do is edit the java.security file in the $JAVA_HOME/jre/lib/security directory.
Find the entry securerandom.source and edit the value to file:/dev/./urandom (instead of file:/dev/urandom)
