It happens when clamav works long time (a couple of days, weeks).
hmm never had that problem here but i think i might restart it every few days for good measure. did you try to report this upstream too ?
This bug is very old so closing it as obsolete (and i still haven'T had that problem on any of my machines) Can you test if this happens with 0.99 ?
