Errno: 45 - Lockf deadlock detection

Question

My SE commands or sym* commands are just hanging. Here is what is see the symapi logfile.

Any one familiar with this errors?

Try using a temporary SYMAPI database, and see if the problem persists:

# export SYMCLI_DB_FILE=/tmp/symapi-tmp.db (make sure /tmp is large enough)
# symcfg discover
# ... try some symcli commands here

If this works fine, the problem is likely with your normal SYMAPI database file. Is the file on a local filesystem, or on NFS or another networked filesystem?

If this also fails, perhaps storapid has a problem. Try restarting storapid.

You could try lsof or fuser to see which process has the file open, or see which files the storapid process has open.

(All this assumes you're running some sort of Unix.)

Please refer to the following page for a brief description of locks and deadlocks with locks ..

http://www.cs.rpi.edu/academics/courses/fall04/os/c10/index.html

The messages you quoted comes directly from your kernel .. There is something wrong with the different daemons trying to lock some files.

Unfortunatly I didn't find anything regarding the messages in our Primus.
