java.lang.IllegalStateException: No read operation

[Trevor]

I am trying to throw a whole bunch of reads at spymemcached via
asyncGet and letting spymemcached combine them in multi-get requests
as described in Optimizations on the wiki. If I do too many requests
(a few thousand) I consistently get this error. Am I overflowing a
buffer somewhere and if so can I increase it's size?

This is a particularly disturbing condition. It basically means
unexpected data came in over the wire. Why this happens is a mystery
to me at the moment. I've got a few bug fixes needing to go into the
next release, though.

this happens running memcached 1.4.1 also - I was hopeful it was
related to bug http://code.google.com/p/memcached/issues/detail?id=72
but apparently not since this is fixed in 1.4.1.

Hello all !
I use memcached-1.2.8 and spymemcached-2.3.1
I put JSON into memcached OK.
But then I receive garbage after GET from memcached:

----------------
garbage: "2ao" before JSON and "0" after JSON.

My browser failed during eval this JSON.

Please, help me.
