The buffer overlow is causing our sequences to crash. Instruments are GCMS only (the GCs run fine). It also happens on a colleagues instruments across the building, and it doesn't seem to matter the age of the instrument, or software being used, just that it's an GCMS. The buffer overflow error itself displays in the software and on the GC control panel. The problem is intermittent. Some sequences run fine, others crash on the first sample. Most of the time it overflows between 4-6am after about 6 samples. But not at an exact time like a scheduled task interference. Our IT and our service company both say there's nothing wrong on their end. No IP conflicts, no network outages, nothing physically wrong with the instruments or computer. I'm at a loss. The start of this did occur after a tropical storm caused a power outage, but I wouldn't think the network card would fail *sometimes*. We didn't install any updates or change configurations recently, and it was working fine previously. I'm thinking of trying a system restore, but would like to avoid it. Any thoughts?
