Re: trying to track GWT timers
just to follow up, I was able to override setTimeout and perform some tracking, record timer IDs and track those that expire, which left me with a single timer that always seems to be present upon shutdown. I am now running code that should close that timer as soon as the app knows it is terminating. only time will tell whether it will have an impact - I'm still waiting to see whether I can reproduce the crash. and, by the way, I tried searching the GWT group for this thread and it returned nothing - the index seems broken.

Re: trying to track GWT timers
I had thought the same. I am running GWT code under MobileSafari on the iPhone and am seeing occasional program crashes on exit. the stack trace seems to indicate that a timer is being fired, and I believe that perhaps the UIWebView has disappeared by the time it runs code expecting it to be there. #0 0x312e5e60 in KJS::FunctionExecState::FunctionExecState () #1 0x312e5b98 in KJS::FunctionImp::callAsFunction () #2 0x312df0f4 in KJS::FunctionCallDotNode::evaluate () #3 0x312e5a78 in KJS::ExprStatementNode::execute () #4 0x312e61c4 in KJS::FunctionBodyNode::execute () #5 0x312e5bac in KJS::FunctionImp::callAsFunction () #6 0x31326ae8 in KJS::JSObject::call () #7 0x328296d4 in WebCore::ScheduledAction::execute () #8 0x32829350 in KJS::Window::timerFired () #9 0x32829208 in KJS::DOMWindowTimer::fired () #10 0x32824c84 in WebCore::TimerBase::fireTimers () #11 0x328249ac in WebCore::TimerBase::sharedTimerFired () #12 0x3282490c in WebCore::timerFired () #13 0x30269d8e in CFRunLoopRunSpecific () #14 0x30269326 in CFRunLoopRunInMode () #15 0x32bc0748 in RunWebThread () #16 0x3146178c in _pthread_body () #17 0x in ??

Re: trying to track GWT timers
Surely when you close the browser window (or navigate away) the timers are gone.
