Summary

• Most of the triggers from LHO happen when
  suspensionMon restarts.
• Several 1-min triggers from H2 occur on MC2,
  corresponding to lock losses
• previous update
• http//www.ligo-wa.caltech.edu/rrahkola/suspensio
  nMon/update_050225.txt
• A few times L1 corner optics triggered
  simultaneously -- unknown causes (power outage
  aftermath? power supplies tripped?).
• Moving forward
• Investigate correlations of interesting triggers
• Minor tweaks to thresholds
• memory leak problem not really a problem (but
  executable size can be reduced dramatically by
  not saving 10min of fully-sampled data for each
  channel)
