Flakey behaviour and error messages

version 2.4.8.5 migrated recently to a new server. we get the following errors. We I did the 2.4.8.1 to 2.4.8.5 upgrade, the upgrade tool reported that all subdirectories were writeable and there were no errors when the upgrade completed. Does anyone have a idea what we should check? thanks. radjr
