Error 1104

Hello,

I have an application that stays running 24/7 and during some parts of the

day can have very heavy volume.

Every once in a while and not at the same place in the code, the program

will error with 1104 - Error reading file. "The operating system returned an

error while VFP was attempting to read the specified file"

If I stop the EXE and start it right back up, everything is good.

Nothing is done to the computer, no reboot or remapping of network drives,

just restart the VFP EXE.

This is a very unique setup. Since VFP is not multi-threaded, there is a VB

program that receives requests from a TCP/IP socket and then passes the

request to one of many VFP EXE's waiting for a transaction.

There can be 2 to 20 VFP EXE's running at the same time waiting and

processing requests.

Everything works great, until the 1104 error starts happening and then all

VFP EXE's get the same error and all have to be shut down and restarted.

It does not happen very often, but when it happens it is a real hassle and

shuts down the operations.

Any ideas on what may cause the 1104 and a possible solution ?

Thanks,

Kent
