In response to an XSTART command or automatic XRC restart operation, the creation of a new XRC address space has failed.
XRC functions are inactive.
Determine the number of active address spaces. If the address space limit for the installation has been reached, you must increase the limit to support XRC. If the problem persists, search the problem reporting databases for a solution. If no solution exists, contact the IBM® Support Center. Provide the system log and generate an SVC dump of the ANTAS000 address space.
