So it's definitely a CURRENT problem. I couldn't spot anything suspicous using ktrace (That is no notable difference compared to the other machine). Here are two excerpts from kdump output that basically repeat all the time: 1262 esd RET read 4096/0x1000 1262 esd CALL write(0x8,0x8059000,0x1000) 1262 esd GIO fd 8 wrote 4096 bytes ... 1262 esd RET write 4096/0x1000 1262 esd CALL gettimeofday(0xbfbfe598,0) 1262 esd RET gettimeofday 0 1262 esd CALL select(0xa,0xbfbfe510,0,0,0xbfbfe508) 1262 esd RET select 1 1262 esd CALL accept(0x7,0xbfbfe580,0xbfbfe528) 1262 esd RET accept -1 errno 35 Resource temporarily unavailable 1262 esd CALL select(0xa,0xbfbfe4f0,0,0,0xbfbfe478) 1262 esd RET select 1 1262 esd CALL read(0x9,0x805c000,0x1000) 1262 esd GIO fd 9 read 4096 bytes
