hello,

today in the tct test mergejobaodandtag  i see:

magfieldathenasvc                                   fatal cannot locate magneticfieldmaps/bmagatlas_09_fullasym20400.data.bz2 from ${datapath}

runtimeerror: (file &quot;&quot;, line 0) std::exception (c++ exception)

it only affects this test. can it be caused by file system glitches? i also saw various tct tests in 16.6.x-val with unreadable output esd today, which is why i wonder.

anyway full log file:
