Octopus scheduled triggers not working

Our scheduled triggers all of a sudden have stopped working. They were all working fine till daylight saving was on and as soon as daylight saving ended they worked for couple of days with delayed time, but later all the triggers have stopped working. Now, even if I add a new trigger it is not working. Any idea what is wrong here? Let me know if you want me to get more details and from where on the server to troubleshoot here. Any help is greatly appreciated because this is creating lot of manual work for us on a daily basis which was smoothly working fine till now.
