  1. Trouble report in the early morning of 22nd, Feb.

  2. Diagnosis (1) • People in the B3 said “something look wrong with NSM.” Status of PC did not get ready. • They also reported that they’ve already rebooted PCs with the problem and it did not solve the problem. • I suspected the nsmd in kani.

  3. Diagnosis (2) • I issued following commands in kani • ps ax | grep higuchi • Gave only 3 processes and one was [defunct]. It should be 4 in a healthy situation. Something is certainly wrong with kani. • ps ax | grep nsmd • Gave only 1 process. It should be 2. One of two nsmd is dead. • ipcs • Gave 3 entries. It should be 4 (2 per 1 nsmd). Because Hara-san deleted one, trying to solve the problem.

  4. Solution • The problem is solved as follows • Stop the remaining nsmd. • /etc/rc3.d/S99nsmd stop • Check by ps ax | grep nsmd • Delete the remaining shared memory • ipcs  ipcrm • Start nsmd. • /etc/rc3.d/S99nsmd start • Restart SVD • In HD terminal, Ctrl+C.

  5. Improvement of the daemon • I will implement the better monitoring. • I will prepare the detailed trouble shooting.
