Hi All

We have a number of Zimbra servers all running Ubuntu using versions from 7.2.0 upwards. For version after 8.0.2 we keep getting servers crashing with the the error below on all of them for version 8.03 upwards including the current 8.0.6. They all have a valid cert and correct dns, hosts etc. Anyone got any ideas here
