For the moment, I have no info on how to reproduce the issue. I was doing nothing when it has crash.

Hopefully, my OS create a coredump. I run airdcpp with symbol on gdb

$ gdb airdcppd

See if this is fixed in the latest build

It seems crashing on the "Incoming refresh time (0 = disable) (minutes)", if my refreshed folder has new files in it

can you open again @maksis ?

[maksis]

Possibly fixed with https://github.com/airdcpp-web/airdcpp-webclient/issues/485 in build 41

Even though the refresh isn't directly related to the uploads, it could be a side effect from memory corruption as the crash log is somewhat strange (no crashes should happen at that location)

So my analyze:

• it took 10 days to have the crash back
• it's not a reproducible one
• refresh time:
  • Auto refresh time = 60 min
  • Incoming refresh time = 15 min

It coincides with the launch (not written in log) of the incoming refresh time (12:32 + 15 min = 12:47)
