Dear Jitesh,

Currently, all EMBOSS applications simply execute.

When they terminate, if EMBOSS_LOGFILE is defined they can write a
single record the the logfile.

However, we can extend this is that is what you are suggesting.

All EMBOSS (and EMBASSY) applications start with a call to ajAcdInit
(often via embInitP or ajGraphInit)

All EMBOSS applications end with a call to ajExit on success. Failed
applications should call ajExitBad or ajExitAbort ... unless they crash
with a segmentation fault or are otherwise terminated.

So we have places to put in additional monitoring code.

This script, could, for example, check the list of known running
applications and remove any that appear to have crashed.

We have no breakpoints in EMBOSS at present. Can you give examples of
what you have in mind?

Hope this helps.
