Hello,
ps -ef cmd in local zones takes about 15 ~ 20 seconds randomly, but work
perfect on the global zone. truss shows the time was spent on pollsys
syscall (went to sleeping) after putmsg.
the most of syscalls made by function traced by dtrace: ioctl(), gtime(),
read() and write(), which were issued by application processes that are all
single-threaded, but it seems that the syscalls are not related to pollsys
sleeping, as the ps slowness happened during the time when ioctl() call
reached over 50000 and over 5000. there are over 40 GB freemem, cpu is
always 80% idle; and shortlived processes took about 07 ~ 1.8 sec out of 5
sec, could the those shortlived caused the slowness ?
is there a way to find what causes pollsys went to sleep ?
Thanks,
James Yang
