Hello! Sometimes starting Squid in OpenBSD 4.9 fails with the following message in cache.log: > diskHandleWrite: FD 10: disk write error: (14) Bad address So far, I was unable to get some more information when enabling some debug options. The only bit of information I was able to gather was a ktrace: > 7990 squid 1319702036.377575 CALL stat(0x3c17e4c0,0xcfbdc7d0) > 7990 squid 1319702036.377577 NAMI "/var/squid/cache/cache-127.0.0.1:24567/0F" > 7990 squid 1319702036.377582 RET stat 0 > 7990 squid 1319702036.377586 CALL open(0x3c17dfc0,0x209,0x1a4) > 7990 squid 1319702036.377588 NAMI "/var/squid/cache/cache-127.0.0.1:24567/swap.state" > 7990 squid 1319702036.377602 RET open 10/0xa > 7990 squid 1319702036.377605 CALL fcntl(0xa,0x1,0) > 7990 squid 1319702036.377607 RET fcntl 0 > 7990 squid 1319702036.377608 CALL fcntl(0xa,0x2,0x1) > 7990 squid 1319702036.377610 RET fcntl 0 > 7990 squid 1319702036.377619 CALL stat(0x89107d80,0xcfbdc76c) > 7990 squid 1319702036.377622 NAMI "/var/squid/cache/cache-127.0.0.1:24567/swap.state" > 7990 squid 1319702036.377628 RET stat 0 > 7990 squid 1319702036.377630 CALL close(0xa) > 7990 squid 1319702036.377632 RET close 0 > 7990 squid 1319702036.377635 CALL open(0x82016680,0x609,0x1a4) > 7990 squid 1319702036.377637 NAMI "/var/squid/cache/cache-127.0.0.1:24567/swap.state.new" > 7990 squid 1319702036.377647 RET open 10/0xa > 7990 squid 1319702036.377649 CALL fcntl(0xa,0x1,0) > 7990 squid 1319702036.377651 RET fcntl 0 > 7990 squid 1319702036.377653 CALL fcntl(0xa,0x2,0x1) > 7990 squid 1319702036.377655 RET fcntl 0 > 7990 squid 1319702036.377659 CALL write(0xa,0x8a624fd0,0x34) > 7990 squid 1319702036.377682 RET write -1 errno 14 Bad address > 7990 squid 1319702036.377694 CALL mmap(0,0x1000,0x3,0x1002,0xffffffff,0,0,0) > 7990 squid 1319702036.377698 RET mmap -2101538816/0x82bd1000 > 7990 squid 1319702036.377705 CALL gettimeofday(0x3c15cdb8,0) > 7990 squid 1319702036.377708 RET gettimeofday 0 > 7990 squid 1319702036.377712 CALL write(0x3,0x7e7dd000,0x50) > 7990 squid 1319702036.377714 GIO fd 3 wrote 80 bytes > "2011/10/27 09:53:56| diskHandleWrite: FD 10: disk write error: (14) Bad address" > 7990 squid 1319702036.377716 RET write 80/0x50 The error is unfortunately hard to reproduce. One of about 10 startups the problem occurs. Thanks for any advice! Greetings, Matthias
