Hi, I’m running syncthing v0.11.26 on my NAS. I’ve been using Syncthing with no problems for around a year. One week ago it stopped working. Whenever I start the program on Windows7 32bit it flickers a few times and exits. I checked the syncthing log and it keeps showing fatal error: runtime: cannot map pages in arena address space. There’s also logs named “panic-2015115” created.
I’ve searched for the solution already, everyone says it’s because I don’t have enough ram, but I’ve been using Syncthing without issue for roughly a year. I have 4GB ram installed.
Another quick question, I use Syncthing between my Seedbox and NAS. They are only connected by one folder, and whenever this folder has new content in it, sickbeard/rage automatically relocates it to a second folder. What I’m trying to say is that my Syncthing folder is almost always empty. You mentioned that I have more data than a year ago, I do. However it’s not stored in my Syncthing folder for more than a day tops. Does this contribute to my fatal error too?
The fact that the data is no longer there doesn’t matter, as syncthing holds history of what was there before. Unless it’s always under the same file name.
Regarding GOGC, check how to set environment variables on your OS.
The amount of historic data we hold for a file that’s no longer there is just a name and a few flags though. It’s not exactly enough to make any difference on an out of memory situation. However we do allocate some memory when scanning a file, and on 32 bit builds this is tight, for large files.
I’m having a similar issue with v0.12.5 and 0.12.6.
I’m just wondering if it is possible to configure the GO Interpreter/Compiler that you put in the Syncthing Executable to allow the use of more RAM on 32-bit builds?
I ask only because I don’t have the ability to upgrade all of my Machines to 64-bit OS’s right now.
