@simonmichal Thanks for playing with it :-). Just to confirm, I upgraded from 5.0.3 to 5.1.1 just now, and this happened only on one machine (our redirector running on a VM). Likely, high traffic / higher I/O latency (as seen in virtual environments) during an upgrade causes this to trigger "reliably". -- You are receiving this because you are subscribed to this thread.
