What sort of condition is your harness in?  A friend of mine in Canada forwarded me a news article of the tragic death of Todd Skinner, who has died due to the belay loop on his harness failing while abseiling from Leaning Tower in Yosemite.

Here's the article: Todd Skinner dies due to harness failure

It's scary to think that

• such an experienced climber could go this way
• the strain on a harness is so much less when abseiling than from taking a winger

Please replace your harness if it shows signs of wear or, at the very least, replace your belay/abseil loop.
