Thus the length of the packet is about 12000 bytes and I send 

( I believe a message can contain 256 items and one symbols can have 

I'm glad if someone points me a wrong point.

I am sending a large packet via udpsend but it always crashes MaxMSP.
The packet has one tag and 40 symbols, each symbols are 299 character  
length.
Thus the length of the packet is about 12000 bytes and I send  
'maxpackedsize 15000' to udpsend.
( I believe a message can contain 256 items and one symbols can have  
1999 characters.)

It happens both on 4.6.2 and 4.6.3.
