The action signature check finally failed for action call

Hi,

WDE reports a problem with action signature:

MessageActionSignatureChecker.checkOk(116) - The action signature check finally failed for action call: XXXX

This is caused by Measurement Threshold policy, that is meant to execute an action when threshold is reached. The action is executed locally on the monitored node. However this error is picked up by wde, not by local agent.

Funny thing is, it looks like the action is actually executed.

We have started to get these errors (picked up by wde log monitor) after modifing the policy to "instance filter" in GUI.

OMi is 10.01 IP4 and OA is 11.14

Anybody has seen this?
