I had big problems with an interface sending big files. (.rtf, and sometimes .png) It (and hopefully will) works ok.
The problem was when we try to load old data. I had a “batch” process to send old messages during night. It worked ok for few days and then… dead!
There was 44961 messages pending. And the bytes out and other stats we’re negative.
The batch process won’t be used anymore, so I won’t have 45000 messages pending anymore but eventually the stat will become negative (I suppose when the integer is too big, the negative bit become 1 so a negative number)
binary(01111111) = 127 +1 = binary(10000000) = -128!
Except having bizarre stats, having a negative numbers of bytes can cause any problem???
