DokanSSHFS.exe CPU usage 100%

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enter to a directory with lots of files using DokanSSHFS.exe
2.
3.

What is the expected output? What do you see instead?

One of two things occurs:

1) Windows displays an error:

"Location is not available, N:\ is not accessible. The parameter is 
incorrect."

when trying to open the drive created by DokanSSHFS.exe 

or if actually opens the correspondig drive

2)CPU usage hits 100% and the program hangs. However, DokanSSHFS does not 
seem to leak memory. In addition, no packets are sent to network.

It seems to me as if there were some kind of infinite loop in the program.

What version of the product are you using? On what operating system?

dokan-sshfs-0.2.0.1226 2008/12/11, Windows Vista Business x86 32-bit.

Please provide any additional information below.

Not sure about "lots of files" - that happens in more or less random fashion.
Also, there's only one process/thread using the CPU that way, as it overloads 
only
one CPU kernel (my CPU has two)

same for me
sometimes 100% cpu usage
sometimes I get "Location is not available, N:\ is not accessible. The 
parameter is 
incorrect."
after trying to access a lot of file like when I want to copy a directory..

same issue here, after accessing some files, DokanSSHFS.exe process randomly 
(and 
quite frequently) goes to 100% CPU (actually 50% on my dual core system), the 
mounted 
drive no longer accessible. 
I used ProcessExplorer to probe the thread eating 100% CPU and the call stack is

ntkrnlpa.exe+0x6e9ab
ntkrnlpa.exe!MmIsDriverVerifying+0xbb0
hal.dll+0x2ef2
dokan.dll+0x61a1
dokan.dll!DokanMain+0x51e
msvcrt.dll!endthreadex+0xa9
KERNEL32.dll!GetModuleFileNameA+0x1ba

I'm using Windows XP Pro, SP3

Well, one correction here, even on dual core systems sometimes DokanSSHFS.exe 
can 
take up 100% CPU (meaning multiple threads are busy looping). I got another 
call 
stack snapshot here

Same problem here, after opening some files in Komodo Edit. After working for 
about
20 minutes the activity will spike to 100%

After opening a file dialog, the Dokan process kicked CPU usage (both cores) to 
90%+
and brought my machine to a crawl.
