MMM-PublicTransportHafas: Service Temporarily Unavailable

[rotorax]

Hi, thanks for your update.
I installed your git version and I had to install undici additionally. Is that correct?

The MM works but ended starting up again and agin:

Im using a raspberry pi zero with 512 MB RAM which worked fine in the past.

Also some system information:

Anyone have the same problem?

@rotorax how big is the swap space?

free -m

Will list that

[rotorax]

@sdetweil

while running and short time before crashing:
user:~ $ free -m
total used free shared buff/cache available
Mem: 426 217 99 19 109 132
Swap: 871 250 621

@rotorax OK try this

  export NODE_OPTIONS=--max-old-space-size=4096

before the npm start

if using pm2 then this goes in the script it launches,
using my setup
MagicMirror/installers/mm.sh

4096 may need to be adjusted

@sdetweil thanks for the idea. I already had this code seen. But never implemented in my pm2 startup file.
I tried up to 512 (limit of the raspberry I have).

Thats the log I got:

I rolled back to the old config before the change of the MMM-PublicTransprtHafas and it run hours (unfortunately I don’t get any live data anymore with the old version)…

More ideas? ;) Grateful for every hint :)

@rotorax i am certain you have to have at LEAST 4096, not smaller, maybe 8192
