Network Stream Max Buffer Size

Hello,

I recall an AE on here once mentioning that network streams can exhibit problems if you set a buffer size greater than 9MB, but I haven't been able to find any concrete explanation of this.  The reason behind me asking is that, I'm currently running into some memory problems in my application in which I initialize my buffer to 30MB.

Basically, my application starts out running fine, but after 30-45 minutes, all of a sudden, my network stream buffer starts building up until it reaches a max value, even though I am still reading data out of it at seemingly the same rate.  It's as if routine memory allocation/deallocation elsewhere in my application causes issues with the network stream.

Anyone have any insight to this?

thanks in advance,
