Description
I think this is what's happening.
Basically, my script is using jack.input with the a specified ID so that jack.plumbing can auto connect the ports to the system captures. I've noticed quite often after Ctrl + C / SIGINT is sent to the process that if I try and start the script again it comes up with something like http://pastie.org/373616 which says it can't find a running jack instance. If I edit the ID in the script to something that hasn't used it's fine, likewise if I restart JACK it's fine. I don't seem to have this issue with other programs, but generally I have little control over their ID (it seems to be program name + PID) so I haven't been able to see if other programs have similar issues (and in which case JACK is not cleaning up).
I'm using JACK 0.116.1, the newest copy.
I found this is a little random, sometimes I can control + C with no issues. It happens probably 1 in 3 times.
Oddly enough, if I send SIGKILL, the issue doesn't seem to happen as much, out of about 15 goes it happened once, which is a lot less than pretty much every other time. Again SIGHUP seems to be similar in the since it doesn't happen as much.
If this is an issue with JACK, maybe you could do a quick hack and have an option to append the PID or something to the end of the channel name. Least it would work round the issue in the short term and still let me use jack.plumbing as it can do regular expression / pattern based rules.
This little annoyance would be great to sort out as it does bug me on my dev machine a lot.

Out of interest, is there any development on this ?
Hi !
I will try to reproduce as soon as possible.
Hi !
I think I see the reason for this issue. It is however more general, so it will be fixed with the more general issue, see #294

China is the world's commitment to implement energy-saving emission reduction targets, to enhance policy support the new energy economy strategy, accelerating the construction of solar photovoltaic technology in rural and urban areas of the application, the relevant state ministries launch solar roofs program. Solar roof planned efforts to break through the integration and solution architecture design of a lack of optical, optoelectronic products combined with low level of construction, optical and network problems, low market awareness of the problem. Solar Roofs Plan into consideration economic and social benefits and other factors, at this stage of economic development, industrial base cities to actively promote a better solar roofs, building integrated photovoltaic curtain wall and other optical model; actively support development in rural and remote areas from the net-generation, implementation of transmission to rural areas, the implementation of the national farmer-friendly policy. Solar roof planned to mobilize all sectors of society through the development of demonstration projects and promote the implementation of relevant national policies. Demonstration projects to strengthen advocacy, to expand its influence, increase market awareness, formation and development of solar photovoltaic products, a good social atmosphere; to promote the implementation of tariff and other Internet-sharing policy, the formation of policy together, amplifying the effect of policies; the optical construction applications as an important building energy efficiency content, in new construction, existing building energy-saving, actively promote the use of urban lighting. Policy limit sun roof demonstration project must be greater than 50kW, which requires at least 400 square meters of total floor area, construction is difficult to participate in the general population, eligible owners will focus on schools, hospitals and government and other public and commercial buildings. Ministry of Finance to consider subsidies, the cost of electricity can be reduced to 0.58 yuan / kWh. Whether PV electricity price electricity price in the thermal power given premium is not clear, but even without the premium, due to lower power generation cost sales price, the owners are still building solar power projects to generate electricity for personal use, replacement power purchased from power. Moreover, local governments can be expected to give additional subsidies, electricity costs will decline further http://solar-poweronline.info/
