ran Trimhistory and it broke something

Per the instructions found at https://xymon.sourceforge.io/xymon/help/manpages/man8/trimhistory.8.html I ran the following command to trim my very old log history and ever since then I'm getting the following crash alert.? Also when reviewing history via the webpage I get results but the time stamps are wonky.? I suspect it's because of the program crashing.
Anyone know how to fix?

Trimhistory command I used:
$ ./trimhistory --drop --dropsvcs --droplogs --cutoff=`date +%s --date="1 Jan 2019"` --progress

Alert I'm receiving:

xymond_history purple [549922]
red - Program crashed

Fatal signal caught!
