Hi there,

I've been using the unserialize and serialize methods in php5 on some
rather large objects it seems that the larger object get the following
errors:

	Notice: `unserialize()`: Error at offset 6167 of 31195 bytes in
	/root/doServerStates.php on line 37

Different smaller object:

	Notice: `unserialize()`: Error at offset 6179 of 21955 bytes in
	/root/doServerStates.php on line 37


The error offset is different based on the the size of the total file. I'm
trying to put together a test case to replicate the issue. I wanted to
see if anyone has already identified this issue before taking the time to
do the test case.

Thanks,
David

Do you store the serialized data in a file betweep the ops? If yes,
check that you use binary mode only. I got similar errors in the past.
