Content-Disposition: inlineHello,

Is there a size restriction on the data or limitation on number of operations when using the personal edition?

I get a crash at exactly the same data insert point. However, the statement is valid (I checked independently) and the time of 2 hours has not been exceeded.

The message is about invalid memory access and Windows shuts down q server.

I am using the logging mode. The size of the disk file is 6.34 MB. I am using WinXP/32. The log file does not have the new record that was sent to the q server.

A rerun goes past the point where the memory access error occurs.

the only limits are 2GB addresable and allocable memory and 2 hours timeout.

check your memory stats with \w before the inserts to see how your q memory is growing.
