What is the problem you are having with rclone?

When mounting occasionally rclone will spit out the error shown below, aside from this everything seems to be working okay. Happy to provide any more information or debug assistance 👍🏻 Also, thank you for this project - amazing stuff!

What is your rclone version?

maxexcloo@server:~$ rclone_rd version
rclone v1.59.0-DEV
- os/version: debian 10.13 (64 bit)
- os/kernel: 5.10.0-0.deb10.19-amd64 (x86_64)
- os/type: linux
- os/arch: amd64
- go/version: go1.18.1
- go/linking: static
- go/tags: none

Which OS you are using and how many bits?

maxexcloo@server:~$ uname -a
Linux bedok 5.10.0-0.deb10.19-amd64 #1 SMP Debian 5.10.149-2~deb10u1 (2022-10-28) x86_64 GNU/Linux

Which cloud storage system are you using?

realdebrid

The command you were trying to run?

~/bin/rclone_rd mount realdebrid: ~/realdebrid --config ~/.config/rclone_rd/rclone_rd.conf --dir-cache-time 10s --use-mmap --vfs-cache-mode full

What's the error?

correction:
These are two different issues:

pic1 - crash at line 530
pic2 - crash at line 696

Answer 5 · 2023-01-19T14:43:59.000Z

These memory panics happen because Im accessing the response status code. Apparently GO does not always return a status code, so I need to try and catch these bits.

Answer 6 · 2023-01-22T15:28:50.000Z

Interestingly it hasn't come up since I changed servers and stopped using a VPN so it may have been that something was blocking/adding latency before.
