Re: [PHP] MS SQL Problem
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi there, I remember reading of a config setting in php.ini which lowered the time PHP waits before clearing up/closing the socket out. If it's a linux system you might want to try running netstat to see the open net connections. If you see lots of open connections when you reload the page a few times to your sql server then you know you need to shorten the appropiate timeouts. If you dont see lots of open connections then it's something unrelated to the actual virtual circuits opened.

Re: [PHP] MS SQL Problem
Thanks for the reply. Actually, I am using both mssql_free_query and mssql_close along with mssql_pconnect. It still happens however. I can post the code if you are unsure. Does it have a history of threading issues as it only seems to happen when several requests are sent all at once or at least in very fast succession.

Re: [PHP] MS SQL Problem
Hiya, were you using the appropriate free_query & close functions to free up the memory & more importantly the socket used to talk to the sql server? You might want to try using the _pconnect function if it's available instead of the usual _connect statement. I'd guess that PHP ran out of sockets to make outbound connections with. Also, I believe that MSSQL is setup to only have around 1000 max connections open unless you alter the value in the config.

echo your select to make sure it looks like it should.

echo the result to make sure it looks like it should.
Doing the above will probably find your problem for you.
