That does not actually seem to tell me what thorn caused the abort, but
it looks as if a thorn was not found. Unfortunately these error messages
tend to be a jumble due to output from stderr and stdout being mixed.
Would you mind checking near the top of the output file if there is an
more detailed error (or attach the full file).

Since you say that the error line is just after the ActiveThorns line
for Trigger, it might be that the executable used does not have the
proper thorn compiled in.

To check you can run
"/scratch/ettest34/simulations/tov_collapse/SIMFACTORY/exe/cactus_sim
-T" which will output a list of the compiled in thorns. You can also run
"/scratch/ettest34/simulations/tov_collapse/SIMFACTORY/exe/cactus_sim -S
/scratch/ettest34/simulations/tov_collapse/output-0000/tov_collapse_vc_l3.par"
to check if the parameter file parses correctly and all required thorns
are present (both do not require MPI so you can run them on the head
node of the cluster).

When you added the Trigger thorn to your thornlist, did you recompile?
One way of achieving this should be:

cd Cactus
# add AEIThorns/Trigger to AEIThorns section
vim thornlists/einsteintoolkit.th
simfactory/bin/sim build --reconfig
--thornlist=thornlists/einsteintoolkit.th
simfactory/bin/sim purge tov_collapse
simfactory/bin/sim create-submit tov_collapse --parfile par/tov_collapse.par

Yours,
Roland
