> Each call to dahdi_restart() increases asterisk RES memory usage in "top".
> Test under valgrind with one single PRI span configured.
> dahdi_restart() called N times (1000 for test), either through AMI DAHDIRestart, or through CLI "dahdi restart".
> Result shows as many "definitely lost" blocks as dahdi_restart() executions.
> It also shows two other memory leaks with fewer occurrences (approximately 25% and 70% respectively).
> Issue initially opened with "minor" severity because dahdi_restart() usually is not a frequent operation.
