...could be a timing dependent issue that only manifests with a particular
FE. My own frontends tend to be used at different times during the week and I
could easily see something like flagging jobs or the fetch from SD being seen
to only interefere with one of my frontends.
I've gone to a bit of trouble myself to try and tweak my mysql database
and later to schedule things so that they would likely not impact the master
backend or the network in general during expected viewing hours. All of my
dedicated myth boxes shut down flagging during "prime time". Although I do
keep my main desktop running 24/7 doing jobs. This also has the side effect
of capping the total number of jobs running across the entire network.
