We recently implemented a new optical storage system using a software package that runs on Windows. The particular machine that is used to host this application gradually had problems accessing the optical storage (which is essentially a NAS device) and would frequently pop the title message: Insufficient system resources exist to complete the required service.
I thought this was a bit odd, considering the machine has 16GB of RAM, Dual Quad Core processors, and at fairly large amount of storage. We kept thinking that there must be a driver issue, or some issue with the software, or even an issue with the optical storage.
I have no way to prove it, because I couldn’t ever tell for sure exactly how the system go to the point of not being functional, but the last thing I tried APPEARS to have worked…
I took out the /3GB switch in the boot.ini.
That was 3 days ago and the system hasn’t had the issue since, even though it had gotten to the point where it was happening several times a day. The thing that tipped me toward this as a possible solution was the fact that everything I read said that this was likely caused by a memory leak, but we didn’t seem to have memory issues (at least when we could get into task manager there didn’t seem to be much activity) and when I came across this post… I took a chance and it seems to have fixed the problem for now.
