Set up an OTP instance taking too long

[kimnewzealand]

I have successfully created a graph object but it seems like there is a potential issue with setting up the OTP instance. See below error message.

log <- otp_build_graph(otp = path_otp, dir = path_data, memory = 1)

Basic checks completed, building graph, this may take a few minutes
Graph built

otp_setup(otp = path_otp, dir = path_data)

2019-05-30 11:05:41 OTP is loading and may take a while to be useable
2019-05-30 11:11:05 OTP is taking an unusually long time to load, releasing R to your control

Trying the other alternative ports example

otp_setup(otp = path_otp, dir = path_data, port = 8801, securePort = 8802)

2019-05-30 11:11:06 OTP is loading and may take a while to be useable
2019-05-30 11:16:29 OTP is taking an unusually long time to load, releasing R to your control

O this one does not appear to be an issue. I tried the memory=1 trick again and it worked so I will close

otp_setup(otp = path_otp, dir = path_data,memory=1)

2019-05-30 12:02:35 OTP is loading and may take a while to be useable
Router http://localhost:8080/otp/routers/default exists
2019-05-30 12:05:47 OTP is ready to use Go to localhost:8080 in your browser to view the OTP

Hello,

I am encountering the same issue:

2020-06-15 01:35:22 OTP is loading and may take a while to be useable
2020-06-15 23:27:51 OTP is taking an unusually long time to load, releasing R to your control, OTP will continue in the background

except the solution posted by Kiminnewzealand did not work for me. I tried:

log2 <- otp_setup(otp = path_otp, 
                  dir = path_data, router="MARTA 2019", memory=1)

and got the error:

Assertion on 'memory' failed: Element 1 is not >= 500.

@mattdpalm are you using the demo data? What kind of computer are you using? Have you checked all the requirments in the prerequisites https://docs.ropensci.org/opentripplanner/articles/prerequisites.html

Malcolm, thank you. I managed to make it work with the demo data. But am now trying to replicate with Atlanta Region GTFS and State of Georgia (USA) OSM. It's a laptop with 16 gig of ram, 64-bit, Windows 10, using the latest V8 of Java for 64 bit.

The whole state of Georgia might be too big to fit in to 16GB of ram. I'd suggest trying a smaller are first like the biggest city to get a feel for how much RAM is needed. Remember to use the memory argument in otp_build_graph and otp_setup

@mattdpalm I'm closing this issue as I don't think your problem is caused by anything wrong with the package.

Hi Malcom, I reduced the OSM street file down to the Atlanta area. The graph was built--it's only 170 mb. But I still receive the error code about it taking too long to run. So the solution is memory=1? Thank you

Hi, @mattdpalm I think you are having the same problem at #65 so can you try the suggestions there and if that doesn't work post on that issue?
