Thanks...looks like major progress here. Two questions: 1) Thomas, when you say you have fixed it/changed the sequence of startup...will that be a new jar to download? .175? 2) Noel, "something running in background connecting to Web Console" - we are running a perl based webadmin tool...I will check that out and see what happens when I disable it
root 1359 1 0 09:25 ? 00:00:00 /usr/bin/perl /usr/libexec/webmin/miniserv.pl /etc/webmin/miniserv.conf I also downgraded to java 6 on the test server and I cannot reproduce the problem (with webmin running). So that confirms the bug was not present in java 6. Upgrading back to java 7 u 51 now to test with and without the webmin...
