The Ping Identity Directory Server version 220.127.116.11 has been released and is available for download. The release notes are available online, but this version addresses two issues:
If an attempt to establish an outbound LDAP connection failed, the server could leak a small amount of memory. Over time, these small allocations could accumulate and could cause the JVM to run out of memory.
In a Directory Proxy Server configured to use entry balancing, a search that spanned multiple backend sets could incorrectly return a result of success if all search attempts within one of the backend sets failed with a timeout. It now returns a result of unavailable.
