Windrop & dzsBot taking 100% CPU

[Mouton]

dZSbot 0.0.8.3
Windrop 1.6.12 (tried 1.6.10 too)
ioFTPD 4.6.2u

I modified dZSbot.tcl to suit my needs... removed stuff I didn't need, etc.

It announces OK.. sometimes from start to end...
But often, I wipe the release, re-up it and then, in the middle of the upload, the bot stops responding and starts taking 100% CPU...
I placed a couple putlog "bla" to see where that happened, and it seems random...
Once, it stopped in sndall function... once in readlog... etc.

Anyone got any idea how I could debug what's hapenning on the windrop ? or even better, how to fix the stupid bot and stop it from using 100% CPU ..?

Thx.
