Yes. The only way to tell whether a libpthread-threaded process is consuming CPU is to watch the TIME column in top or ps and see if it's incrementing. You can also switch to libc_r or libthr via libmap.conf, both of which should correctly report CPU (although libc_r is going to be slower, and libthr is not as stable as libpthread). A possible workaround for this might be to have top inspect the process' rusage struct and display that in the CPU% column. -- Dan Nelson dnelson@allantgroup.com
