But when Claws-mail stalls, it gives the following multiple times: read(4, 0xf48704, 4096) = -1 EAGAIN (Resource temporarily unavailable) select(5, [4], [4], NULL, NULL) = 1 (out [4]) writev(4, [{"xxxxxxxxxxxxxxx"..., 108}], 1) = 108 select(5, [4], [], NULL, NULL) = 1 (in [4]) read(4, "xxxxxxxxxxxxxxxxxxxxxx"..., 4096) = 108 Well, I hope this time you have more information and I hope I didn't forget anything. If not, let's keep trying. Important: these data were collected with frto disabled (0) and htb disabled too. So it isn't related to frto, neither htb.
