Oracle10.2 RAC节点中，查看crsd.log的时候发现有很多 th_select_handler message
crsd.log: th_select_handler message 是可以忽略的信息
[ OCRSRV][3864]th_select_handler: Failed to retrieve procctx from ht. constr = [399766928] retval lht [-27] Signal CV.
[@more@]crsd.log: th_select_handler message repeated
[ OCRSRV][3864]th_select_handler: Failed to retrieve procctx from ht. constr = [399766928] retval lht [-27] Signal CV.
metalnik上说:不用理会，可以屏蔽
Cause
This is an informational message for development.
Solution
This message can be ignored as described in internal bug 4494370.
Schedule a maintenance window and turn off this messaging as user root on one of the clusternodes:
# crsctl debug log crs OCRSRV:0
Stop and start CRS after changing the tracing level to pick up the change.
运行这个命令后就没有th_select_handler: Failed ...的提示了
