Hi,
I promised to get back to the list.
False alarm, it was a carbon unit failure.
write blob does NOT lock the server when sending HUGE files.

I'm send a large PDF (70MB) to a browser using write blob.
Whilst this is happening all other users cannot do anything on the server, as soon as the download is finished the other users can access the server fine.
Am I doing something silly?
Yes, you are trying to send a 70MB file using 'write blob'. ;-)
Obviously 70mb is a large file and I expect it to slow down other users due to bandwidth restrictions, but what we seem to be seeing is all other processes are frozen until this is complete.
Active4D doesn't handle the actual sending, so I think the hangup is in the 4D command SEND HTML BLOB. My guess is that this is blocking all other processes until it is done.
The function PM2_PDF_TO_BLOB loads the file from disk into a blob and returns that in $0
The blob is sent and received successfully (so it doesn't appear to be a memory error).
Any ideas?
If in fact SEND HTML BLOB is blocking, you will have to give your users another way to download.
