You can safely ignore this. There is an open issue [1] for this is the DAHDI-Tools project on the issue tracker.

This looks fine then and it's most likely a result of the dahdi_test process not being scheduled on your system in a timely fashion. Your cummulative timing results were 99.997% which is good. What do you get when you run: $ chrt -f 99 dahdi_test -v -c 5 That will run the dahdi_test process at the highest possible priority. -- Shaun Ruffell Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com & www.asterisk.org -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-ss7 mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-ss7 CONFIDENTIALITY / PRIVILEGE NOTICE: This transmission and any attachments are intended solely for the addressee.
