新接手一个RAC环境，版本x86_64 Oracle 10.2.0.1，crsd.log频繁的出现警告，内容如下：

查了一下，主要是两个内容

1.2011-04-18 11:46:42.766: [ OCRSRV][1273047392]th_select_handler: Failed to retrieve procctx from ht. constr = [-1734323776] retval lht [-27] Signal CV.

ID 338693.1

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This message can be ignored as described in unpublished bug 4494370.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

看来，升级还是必须的
