Not really, sorry, but it reminds me of a timeout. Something trying to load something from a service not responding. I’d check if one of the components is trying to reach a server which is unresponsive and if DNS resolution is ok. Sometimes delays occur if a wrong DNS server is configured and the system uses a fallback DNS when the primary one is unresponsive. Or an applet trying to access a resource which is not available. E.g. trying to show free space of a drive which is not mounted.
