FTL Crash

Thanks for your report and sorry for the delay in replying - it's busy times!

Could you please run the following commands and tell me the output (if there is any, but I do hope so):

addr2line 0x5cccd -e /usr/bin/pihole-FTL

addr2line 0x5ea15 -e /usr/bin/pihole-FTL

addr2line 0x62539 -e /usr/bin/pihole-FTL

Good afternoon, thanks for taking the time to look at this issue. I'm assuming I've done something wrong with the setup or something, especially as both servers crashed after I loaded the admin page.... but I appreciate your time in looking at the issue. One thing I am working on is renaming all of my AP's. Looking at the log file, there are miles of logs that "replaced invalid characters in hostname". All of our ap's have a space in them, and we have 20 or so at each location, and they're also our most "vocal" devices on our networks. I still wouldn't think that would cause a problem. Also, the resources to the VM were way over provisioned, even during the heaviest usage, the CPU utilization never went above 20% and it was using less than 1 GB of the assigned 8GB... Let me know if there is anything other information that is needed.

Server 1 (GPM):

Thanks.

Spaces are illegal in hostnames which are nothing else than domains. There's also no possibility for something like www.github.com. Some routers/systems allow you to specify such standard-violating hostnames but Pi-hole should be able to handle them.

Looking at the lines you posted, we see that the error happens here:

FTL/src/api/api.c

Line 229 in 0122731

temparray[domainID][0] = domainID;

which is actually bit puzzling as this shouldn't be able to crash... The only reason I could imagine right now would be if you have an outrageous number of domains in your memory - however, we have seen reports of Pi-hole being employed at the network provider-level and there was never such a crash anywhere.

As such, I am not sure which direction we could go right now to provide a fix for the issue you are seeing. However, what I would recommend at this point would be you trying the all-new Pi-hole v6.0 which is currently in late beta phase and should go live soon(ish).

See more details here: https://pi-hole.net/blog/2023/10/09/pi-hole-v6-beta-testing/

As the entirety of the API has been rewritten, I doubt this crash will still exist.
