A large udp packet crashes Max


    May 17 2007 | 12:33 pm
    Hi All,
    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.)
    I'm glad if someone points me a wrong point.
    It happens both on 4.6.2 and 4.6.3.
    I'm using MacBookPro (2.33GHz), Mac OS X 10.4.9.
    I attached my patch and crash log.
    Thank you in advice.
