I believe the exception is caused by <a href="show_bug.cgi?id=312457">Bug 312457 </a>, which, in turn, is caused by a Java bug: InterfaceAddress.getNetworkPrefixLength() does not conform to Javadoc http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6707289 Reporting the error to the client application is not really possible, because clients of Locator service are remote machines, and the error indicates that clients are not accessible. Log file seems the best place to report such errors. Probably the best fix would be to report the error only first time it happens, and suppress consequent reports. Fixed. Now Locator services does not log same error more then once. Looking at the time when this was fixed, it got fixed in TM/RSE 3.2. *** Bug 338650 has been marked as a duplicate of this bug. *** Moving bugs to new home for IP log. Bulk change: Marking all bugs from the TM era (until June 2011) target 0.3 |
CQ:WIND00210473 Build ID: TCF HEAD of November 2009 I'm unsure what's triggering these messages, but I'm seeing lots of errors logged like the following when my Firewall is on. I would expect errors like this to be reported to the client application for proper handling, rather than just logging to the error log. From the error log, an end user cannot understand what's going wrong or how to alleviate the problem.
