With 500 AIO-SX subclouds, the file descriptor (fd) usage for the dcorch-engine processes is higher than expected. The open file descriptors are about 13,000. The majority of the file descriptors (almost 99%) are idle network sockets. This update removes statically open connections that are not used or not needed. Since both sysinv and dbsync clients are not session-based they will not take advantage of an already authenticated session. Cached clients are still used for both sysinv and dbsync clients. The test result shows the number of fds have been reduced by more than 94%.
