I have a project which used many valueChanged events and worked well ,but today all valuechanged events suddenly stopped working due to some unknown reasons.I am using Ignition 7.7.5 , and I use valueChanged events like :   
from org.apache.log4j import Logger  
if currentValue.value == 1:  
log = Logger.getLogger(“test”)  
log.error(“test error”)  
do somethins …  
system.tag.write(tagPath,122)  
when I changed the tagvalue to 1,the scripts didn’t work,the value kept as 1.  
After I restarted the ignition services ，everything worked well.  
Anyone ever come across anything like that?

Did you ever figure this out, I’m having problems getting the valueChanged script to run unless I disable or reenable a tag. Thanks
