WP4464. Brian, Fabrice and Dave.

Following the restarts of all the recompiled front ends yesterday Fabrice noticed that the BSC ISI watchdogs were being reset a few seconds after tripping.

We tracked the problem down to a modified common C-code file which was installed on the HAM ISI systems but not on the BSC ISI.

The C-code is isi/common/src/ISIWD_GPS.c. Its number of inputs was increased to accomodate the hardware watchdog system. The HAM ISI common model (isihammaster.mdl) was updated to the new code but the BSC common model (isi2stagemaster.mdl) was not.

The solution to get the BSC ISI systems operational today is to make a copy of the older version of ISIWD_GPS.c called ISIWD_GPS_OLD.c and change the isi2stagemaster.mdl to use this file (with the smaller number of inputs) in both stages. Brian and Fabrice will now work on isi2stagemaster to use the new code. For now LHO's isi2stagemaster.mdl will remain a locally modified not submitted to SVN, and the ISIWD_GPS_OLD.c will remain a local file not added to the repository.

We built,installed and restarted h1isibs and Fabrice tested the watchdog, it is functioning correctly. We will restart the rest of the BSC ISI this afternoon when the opportunity arises.
