Error message QVX

[#1]

Hello,

i have a unknown Error message when i reload a script that connects to a SQL Server and load a table.

First i have the message "QVX_unknown Error" in the script window of the fat client. Than i filtered the table and in a smaller load version it shows me the

Error "QVX_PIPE_ERROR" ...what can be the Problem?

I too have a customer experiencing this error intermittently on SQL Server. This thread references a bugid

Not sure if it's applicable to SQL Server.

We had our QV environment redesigned with new and more powerful and dedicated loading servers and the error disappeared. I can still reproduce the error on our test server when loading our 'biggest' applications. The test server is sized half in ram memory compared to our production loading servers. We use virtual machines as loading servers with 50 Gb ram and 10 cores on each without issues.  I would suggest to setup a virtual machine if possible and double the amount of ram on that machine and run the loading that fails and see what happens. When upgrading from v 9 to v 10 the amount of ram used for loading increased dramatically for us. We did an investigation of memory usage together with our QV partner and QT and came to the conclusion that the memory was insufficient for our loadings in v 10. However, the loadings in v 10 were alot faster.

It can be a performance issue. When i had this errror message i had a 12 GB Server with 4 Cores and the tables had more then 75 million  data sets.
