Spider Poison still acts after dispell

[zeroaster]

Hello on the server Project 1999 my character a lvl 7 shaman experienced in East Commons a spider poison spell that endured after i cast my dispell poison spell with shaman twice and the symbol disapeared, and my life meter was a solid grey on the inventory screen - yet it continued to drop down further and further. was strange, just thought i'd mention what i noticed, not sure if it was something else, but i certainly wasnt being attacked.

Thanks for your assistance
