metalink找到一篇文章Bug 6850110 : TH_SELECT_HANDLER MESSAGES IN CRSD.LOG ON BOTH NODES
PROBLEM:

--------
- Although turn off this messaging as user root on both nodes using the 
following syntax "crsctl debug log crs OCRSRV:0 " as recommended in Note 
338693.1

提示根据文档ID 338693.1使用crsctl debug log crs OCRSRV:0处理

crsd.log: th_select_handler message repeated (文档 ID 338693.1)



	SYMPTOMS



	In the Oracle10gR2 crsd-logfile ($CRS_HOME/log/<nodename>/crsd/crsd.log) you will find messages like this:



	2005-10-21 13:08:05.702: [  OCRSRV][3736]th_select_handler: Failed to retrieve procctx from ht. constr = [15299816] retval lht [-27] Signal CV.



	CAUSE

This is an informational message for development.

	SOLUTION

This message can be ignored as described in unpublished bug 4494370.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.

该错误只是development的一个message，该错误可以忽略，如果看着不爽，可以在两点节点以root用户执行如下命令解决：


# crsctl debug log crs OCRSRV:0
