I'm having some odd issues since a while.

Running 3 BlueFuries and 1 BiFury USB miners (WinXP SP3), my cgminer started crashing every few days some weeks ago.
Looking at the Task Manager, I found out its RAM usage is increasing all the time, presumably running into some kind of RAM limitations (it's an older centrino notebook with 1.5GB of RAM).
After a day, I see it at about 60MB use of RAM, a day later it's at ~150MB, another day later roughly 350MB+ (which is about the area when it becomes very crash-prone, including using any of its basic menu functions that then can easily crash the application).
Generally its RAM consumption increases at about 4KB/sec.

The BiFury firmware was updated to V1.3 90deg version, which didn't change anything basically. The cgminer directory and executable are manually excluded from any antivirus scan that could interfere.

Could it be recent cgminer versions have some form of memory leak when operating this combo? I remember running just the 3 BlueFury devices for weeks (cgminer 3.8.4) never had this issue.
Only after adding the BiFury, I experienced this behaviour, so I think it's possible that it comes from the BiFury code portion running.
(so far I ran 3.8.4, 3.8.5 (BiFury added), 3.9, 3.10 and now 3.12).

Since the notebook is old, however, and if noone else is seeing such issues.... Could be my hardware of course. It's running pretty cool and the Notebook hardware basically is mostly idling along, so at least it's clearly not running into heat issues. Miners are cooled with a big USB fan and operated off an external powered USB hub.
