DAQ events : olserver52 frozen or network troubles

Below the report of 3 same kind  of events where all the data are lost during 10-20 seconds:

For each event :

  • All the TolmFrameBullder servers are unable to sent theirs frames to the FbmFE server running on the olserver52 host
  • The Imaging servers have some difficulties to sent theirs frames to the FbmMain server running on the olserver52 host
  • the SlowFrameBuilder servers running on the olserver52 host seems stuck during 10 or 20s even if they are running on different CPUs

It's difficult to decouple  if the trouble become from the olserver52 host or the IP network  . Investigation inprogress
