@enkiv2 I've seen this bug report sometimes and I don't think it's caused by some rogue user content, because the input to "NumsFile.saveFile" is not user content, it's the size of the log. I would suspect it has to do with your database log being huge, or then some logic bug in ssb-db2 which is hard to reproduce and fix.
Unfortunately, you're right that I don't have the bandwidth to fix these issues and also I don't see it being worth it long-term to maintain a system that will inevitably die, if not by other factors, then definitely by out-of-memory crashes, as it already is true e.g. on your phone.
