Last week we upgraded our QlikView Server from 11.2 SR3 to 11.2 SR12, since that point we have been seeing in our server logs the following warnings.
Warning PGO: Failed to access shared PGO file: \\abc\Administration\Root\QvsRoot\CalData.pgo.
Warning PGO: Failed to open \\abc\Administration\Root\QvsRoot\ServerCounters.pgo. Error : Encountered a sharing violation while accessing \\abc\Administration\Root\QvsRoot\ServerCounters.pgo.. Time: 10780 ms
Warning PGO: Failed to access shared PGO file: \\abc\Administration\Root\QvsRoot\ServerCounters.pgo.
We have a clustered server environment, so the PGO files are in a shared folder that is accessible to all servers. Just a quick note we replaced the 2 servers that were hosting the Distribution service, but the servers that were hosting Qlikview Server, QlikView Distribution Service, QlikView Management Server and IIS didn't change. I have found that on the 3 servers hosting QlikView Server, QlikView Distribution Service there are still PGO files on the local folders in C:\ProgramData\QlikTech\QlikViewServer, just wondering if for some reason these would be causing issues, or is it possible that my PGO files got corrupted somehow. It doesn't appear that the warning messages happen all day, but typically in the morning.
I have included the PGO warning messages that happened this morning. Just wondering what these messages mean and if there is any fix.
