IPY00006505 34425 CSP When running CSP applications with 120 or more channels, a
stuck channel may occur occasionally when the TDX_BARGEIN
event is missed during CSP operations.
Workaround: Stop all cron jobs while running high channel
density CSP applications.
IPY00010138 33783 CSP An HMP system failure may occur in an application with channel
densities above 40 running on a computer with 256K cache or
less.
Workaround: For channel densities above 40, use a computer
with Intel® Pentium® 4 processors that have greater than 256K
cache (default for newer computers is a cache size greater than
512K). The size of the cache on the machine can be
determined by looking in the file /proc/cpuinfo.
