Re: Question about max size of a dbrpcparam

I tried with v0.82 and the same problem exists. I traced through the code
and naturally it is spending a lot of time in this function:

write.c -> tds_put_n(TDSSOCKET * tds, const void *buf, int n)

n = 40841216

The block size is 512; so it seems to be putting 512 bytes on the socket at
a time. I'm wondering if that is the problem; since doing 512 bytes at a
time of a 40mb file takes a while. One thing to note is that during the 'big
for loop' thats in that tds_put_n function; the TDSSOCKET->STATE changes to
TDS_DEAD. Dont know why.

The log file itself is about 200mb; so I really dont have a way to send that
but here is the last few entries in there
