I'm using the new FSEventStream API of Leopard, to monitor changes in some directories. First I had to monitor only one directory and everything worked fine but now I have to monitor another additional directory and now Starting the Event Stream results in the following error:

(CarbonCore.framework) FSEventStreamStart: register_with_server: ERROR: f2d_register_rpc() => (null) (-21)

I'm using the following code, to setup the FSEventStream:

const void *paths[3] = {
CFStringCreateWithCString(NULL, aslfContext->cachePath, kCFStringEncodingASCII),
CFStringCreateWithCString(NULL, aslfContext->licensePath, kCFStringEncodingASCII),
NULL
};

CFArrayRef pathsToWatch = CFArrayCreate(NULL, paths, 2, NULL);
CFAbsoluteTime latency = 3.0; /* Latency in seconds */

FSEventStreamEventId eventID = kFSEventStreamEventIdSinceNow;

struct stat licensePathStatus;
stat(licensePath, &licensePathStatus);
dev_t device = licensePathStatus.st_dev;
aslfContext->stream = FSEventStreamCreateRelativeToDevice(NULL,
&CheatAttempt,
callbackInfo,
device,
pathsToWatch,
eventID,
latency,
kFSEventStreamCreateFlagNone);
FSEventStreamScheduleWithRunLoop(aslfContext->stream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode);
FSEventStreamStart(aslfContext->stream);

The code above doesn't work. But if I change the line:

CFArrayRef pathsToWatch = CFArrayCreate(NULL, paths, 2, NULL);

to

CFArrayRef pathsToWatch = CFArrayCreate(NULL, paths, 1, NULL);

It works flawlessly. But with just one directory.

Any Ideas?
