Help with Chi building Macro - WW Monk 5.4.8

Could anyone please help me figure out why this macro keeps locking up.
It goes from working great to locked up. If I can just get it to stop locking up it works very well for me.

This is just for building chi and keeping tiger palm on target. I hit Combobreakers and RSK and cooldowns seperately.

#showtooltip Jab
/castsequence reset=8/target/combat jab, Tiger Palm, disable, null
/castsequence reset=0.5 0,0,0,jab,jab
/castsequence reset=0.5 0,0,Expel Harm
/castsequence reset=0.5 0,Touch of Death
/castsequence reset=5 jab,tiger palm,Chi wave
/cast Energizing Brew
/targetenemy [noharm][dead]
/startattack

Any help is appreciateā€¦
