Has anyone else seen an issue where the PostgreSQL stats collector will get into a loop on poll/EINTR? This seems to be happening a LOT on my amd64 -CURRENT from 6/16 sources. I don't *THINK* it's a PostgreSQL issue, as this same code runs fine on 6-STABLE. the ktrace of the process is full of: 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call 9788 postgres CALL poll(0x7fffffffd4b0,0x1,0x7d0) 9788 postgres RET poll -1 errno 4 Interrupted system call # if I kill it off, it'll go back to normal for a while, then get into that state again. this is on a dual 5120 system (4 cores).
