Re: 'Phantom' connections?

Posted in 2000

Summary

A poster (bob) worried about 14 'phantom' oninit processes seen in ps -ef after tuning buffers and LRU values. Zandy said they were page cleaner (flusher) threads. Art S. Kagel added that the sessid 0 entries are normal and only record the oninit processes' connections to shared memory. Resolved: not a problem.

Not to worry. This is normal, I've got hundreds of them. These sessid 0 'sessions' just represent and record the connection addresses of the various oninit processes to shared memory. Art S.
