It is related to memory. However, not really tied to how much free memory is available on his machine. Like I’ve mentioned many times before… FDIMPLES is just a front end UI. Actual installation and removal of packages is done by FDINST (part of the FDNPKG package). For the end user, this isn’t important. However to install some really big packages, FDINST requires a lot of low memory. This means FDIMPLES has to have a very small memory footprint. FDIMPLES looks simple. However, it correlates multiple pieces of data. Something like as little as 1 up to about 8 different metadata files and a handful of other data points for each entry. All of that is pulled through something that resembles a prioritized cache. As it runs out of memory, it discards less important data first then ever more important data until sufficient memory is available to complete its current task. Basically with the extreme memory constraints placed on it. Sometimes, it gets stuck needing some low importance data and is forced to hold onto or keep recaching the same data. Just having FDIMPLES reserve more RAM for itself would fix it. But, then insufficient memory would be available to FDINST to install some of the really big packages. The current version of FDIMPLES improved this a lot. But, it still does happen far to often (like at all). I just need to find the time to completely resolve it. With the little RAM it is permitted to consume, I’m often amazed it manages to work at all. :-) Jerome _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
