As far as my experience goes, these messages are only for ones linked with libpthread. If the same application is linked with libthr, these messages go away. As I post about the same issue on -CURRENT a few days ago, I guess these messages are caused by the programs which access process states. ps(1), top(1) etc. Because if I run the following command on the test target machine, I can easily get them. % sh -c "while true; do ps ax >/dev/null; done" I hope this issue will be fixed before 6.1-RELEASE. ---- Kazuaki OdaReceived on Fri Feb 24 2006 - 04:40:38 UTC
