Is there a known issue trying to run 5 or more BFL singles under windows in either 2.4.1 or 2.4.2? 2.3.6 seems to be able to handle 5 singles fine. But every time I try to run all five under a single instance with 2.4.1 or 2.4.2, I get a crash in libpdcurses.dll.

Faulting application name: cgminer.exe, version: 0.0.0.0, time stamp: 0x4fcad128
Faulting module name: libpdcurses.dll, version: 0.0.0.0, time stamp: 0x4f460f95
Exception code: 0xc0000005
Fault offset: 0x000012fe
Faulting process id: 0xb24
Faulting application start time: 0x01cd419e02e067d8
Faulting application path: C:\Users\miner\Desktop\cgminer-2.4.2-win32\cgminer.exe
Faulting module path: C:\Users\miner\Desktop\cgminer-2.4.2-win32\libpdcurses.dll

I think I saw a thread elsewhere here that said if you increase the size of the command window in windows, it might solve this problem.

Yes, increasing the size of the command window (before starting cgminer) has helped people with similar symptoms.

(EDIT: I've seen you already got it working.)

To set a larger size as a default, hit start->run and type in cmd.exe; then click the black system icon in the top left corner of the command window that pops up. Choose 'properties'. The important thing here is the 'Layout' tab. Specifically Window Height. Set the Window height to 40 or 50. You can change the font as well to make it fit your monitor better. Click ok. You may then exit the command window. Any command window you open after this will come up with its new size.

There is a difference in how different versions of cgminer behave with Singles. 2.3.6 worked perfectly for me with up to 15 Singles. I since moved to 2.4.1 (and now 2.4.2) and have found that, using the same command line and command window layout size, 15 Singles crashes it. 2.4.1 are happy with 10 Singles, but not 15. 2.3.6 works fine with 15.

I don't know what broke between cgminer 2.3.6 and 2.4.1. It also behaves differently when Singles go offline; 2.3.6 just exited (which was good) but 2.4.1 and 2.4.2 just mark them as 'OFF' and do not exit (bad).

Win 7 x64
9x BFL Singles
10 Port powered USB hub

Issue: Neither 2.4.4 nor 2.3.6 will start more than 6 BFL singles

Troubleshooting:
- Multiple restarts usually resulting in BFL singles receiving different COM numbers than previous reboot
- Powering and unpowering USB hub
- Plugging USB hub into multiple USB 2 ports will cause zero BFL singles to start in cgminer
- Plugging into USB 3 port will allow 6 BFL singles to start in cgminer, but I receive a, "This device can perfom faster when plugged into a USB 2.0 port," message
- Plugging the 3 BFL singles that where not starting in cgminer into another computer directly to the front USB ports. None would start resulting in same COM errors (2.4.3)

At this point I'm trying to figure out if the USB hub, cables from hub --> singles, cgminer, or the singles themselves are the point of error. All singles light up and the fans spin. Any help would be greatly appreciated.

I'm pretty sure I've seen this before. If you resize the window cgminer runs in, it might fix it.

Window size is already set to 87x56. I've tried increasing it upto 90x80, but it has no effect.
