I see lots of socket files left in /tmp file system on AIX nodes.
[/tmp]
(webadm)mpr3l7>>ls -ltr MQ*
srwxrwxrwx 1 mqm mqm 0 Jun 07 2005 MQSeries.26592
srwxrwxrwx 1 mqm mqm 0 Jun 07 2005 MQSeries.24838
srwxrwxrwx 1 mqm mqm 0 Jun 08 2005 MQSeries.79706
srwxrwxrwx 1 mqm mqm 0 Jun 08 2005 MQSeries.33624
....<snipped>
What are these? Why do they survive QMgr restart? |

is there shared memory left? (ipcs -a )
is there a problem or is it just an inquiry?
/tmp is cleaned on reboot anyway.

Channel processes receive command msgs via these files. The file is cleaned up if the channel ends normally; if it is killed or crashes, the file is left. The qmgr does not know of the existence of the files, so they are not deleted by any other mechanism.

interesting. Can anything be learned from these files? (I don't have some at hand right now...  )

icps -a shows quite a lot.
It is weird these sockets also survive server reboots. The ones I listed are from June 2005. The server was rebooted recently. |

No, all it shows is that you don't have any procedures in place for clearing up "stale" files in /tmp.
Cheers,
