Today SapHostAgent 721 PL9 was released. It contains 3 fixes described in separate notes:
2264155 – Saposcol parent process dumps at startup
2264242 – Unwanted 10s collection interval in saposcol
1984681 – Saposcol data not updated, saposcol hanging (note was valid for SUN, now also for Linux)
One additional fix was just formatting of the help output on command line. The summary note 2180933 has been also updated.
Feel free to let me know if I can enhance the note text to be more understandable.
