The import of a Package via "uniimp PKG" generates a thread leak (one per package) on UVMS.
Importing a lot of packages may cause the UVMS to eventually stop responding to new queries as soon as the Thread Pool is exhausted ( by default 2000 threads).
Thread not released after importing the package.
Update to a fix version listed below or a newer version if available.
