I did setup a small service that should only watch if my other services I want to monitor runs, and if not, start it again and place a message in the application eventlog.

Instruments leaks says that this code leaks: NSString *name = [file substringToIndex:i]; Layer *actualLayer = nil; for (Layer *lay in layers) { if ([lay.layerName isEqual:name]) { actualLayer = lay; } } name is the leaking object. There are some strange things: it only leaks sometimes, not always (this snippet of code ...

While testing application performance, I came across some pretty strange GC behavior. In short, the GC runs even on an empty program without runtime allocations! The following application demonstrates the issue: using System; using System.Collections.Generic; public class Program { // Preallocate strings to avoid runtime allocatio...
