Database size around 4 GB, after each backup the memory usage increases 2-3 GB, till server crash without memory ..
Only if i stop the Firebird service after the gbak -b , the memory will be released.
To change the default FileSystemCacheSize = 30 -> 10 doens't fix or alter the problem
Only FileSystemCacheThreshold = 0 fix the problem, BUT this is a bad possiblity, because then the Firebird server has slow performance.
in 24/7 production this is a big bug. I cannot do a backup all 6 hours as used before, had to change to one in the night, and stop/start Firebird Service.
No other process i know has this memory eating issue. And its not good to say, this is a windows problem, because if i stop firebird service the associated file cache also
is released. Therefore i think its an issue in the pair: Firebird Service and GBAK Utility.
