Question of a Message in PI SDK

Dear,

 

I have setup two EMDVB interfaces redundant on a Test PI system at a customer. The interfaces have already runned and they worked as expected, but then we have turned them off so the PI Data archive on the test system get to full with data.

For some testing I need to turn on the EMDVB interfaces again. They Start to recover the data from the moment they have been turned off till now. the interfaces start up as expected, but after some time I get the following message in the message log of PI SDK: "Failed to retrieve snapshot value of PIpoint: (PI Tag name). COM Error [0x80040524]: Failed to retrieve snapshot value from server. [-214689304] Unknow Warning". The tag that has this error is the fail over tag of the EMDVB interfaces. I don't see other PI tags that will ge created by the EMDVB interfaces that got this issue.

Can some help me out with this issue?

 

Also have search on the internet if someone has already faced this issue and there is some item on the PI Square that is kind of simular to this issue. There someone advised to check the tuning parameters on the PI server and/or PI data archive, due to there are to many request on the snapshot at the smae time or create a case at the OSI soft support. Is this the same case for the issue i'm facing at the PI system of the Customer?

 

Thank you a lot for helping me out.

Kind Regards

Kevin
