I've tested it with Kernel 2.6.7 and Kernel 2.6.8, this could be the problem...

same results on kernels later than 2.4.22!

post your agi... this must be an issue with your script and not asterisk as we use agi DAILY without issues.

If not your actual AGI, at least an AGI which demonstrates the problem so we can try to duplicate it.

Well, I can't replicate the problem any longer. Same versions of asterisk and AGI.

Can't reproduce.
