[LDM #FLA-146766]: ldm file writes



Steve,

The filings of the metar to local disk and network disk should be identical
because both actions are "STDIOFILE -close ..."; Consequently, there
*should* have been a similar "fl_removeAndFree()" message logged for the
filing to local disk. The fact that there wasn't would seem to indicate that
the processing that was actually occurring wasn't "STDIOFILE -close" for the
local disk.

Odd. That command should have caused all pqact(1) processes to close all 
open file descriptors and re-read their configuration files.

How many pqact(1) processes do you have. Does each one have its own
configuration-file?

None.

I don't see how. A small queue might cause the pqact(1) process to miss a
product (in which case it would log a warning) but it shouldn't affect a
product being processed.

Please keep me apprised.

Steve Emmerson
