      The jgroups.uuid_cache.max_elements system property can be used to increase the size of the logical names cache.

    Description

      This is related to JGRP-918.

      The UUID class keeps a static cache of logical names, which is shared by all the clusters running in the same JVM. When TP receives a VIEW_CHANGED event, it calls UUID.retainAll(members), which marks all the addresses on other clusters for removal. If there are enough members to exceed the logical names cache capacity (500 by default), some of those members will be actually removed from the logical names cache and their addresses will be printed as UUIDs.

          Bug - A problem that impairs or prevents the functions of the product. JGRP-918 Logical addresses: removing a logical name or UUID/PhysicalAddress mapping on a view change is incorrect

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.
