Hello! Every once in a while FireFox gets "stuck" on my machine consuming all available CPU. Attaching a debugger to the process shows a stack like this: #0 0x0000000803119a38 in read () from /lib/libc.so.5 #1 0x0000000802f9edfb in read () from /usr/lib/libpthread.so.1 #2 0x00000008008858f6 in PL_EventLoop () from /opt/lib/firefox/libxpcom.so #3 0x0000000800885560 in PL_ProcessPendingEvents () from /opt/lib/firefox/libxpcom.so #4 0x0000000800886f77 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #5 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #6 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #7 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #8 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #9 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #10 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #11 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #12 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #13 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #14 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #15 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #16 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #17 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #18 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #19 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #20 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #21 0x0000000800887012 in nsEventQueueImpl::NotifyObservers () from /opt/lib/firefox/libxpcom.so #22 0x0000000808748429 in nsXMLHttpRequest::RequestCompleted () from /opt/lib/firefox/components/libxmlextras.so #23 0x00000008008a1f27 in XPTC_InvokeByIndex () from /opt/lib/firefox/libxpcom.so #24 0x0000000803994a9d in XPCWrappedNative::CallMethod () from /opt/lib/firefox/components/libxpconnect.so #25 0x000000080399c6f9 in XPC_WN_CallMethod () from /opt/lib/firefox/components/libxpconnect.so #26 0x00000008006808fc in js_Invoke () from /opt/lib/firefox/libmozjs.so [...] According to ktrace, all it is doing is: 92514 firefox-bin CALL read(0x3d,0x7fffffffb4a7,0x1) 92514 firefox-bin RET read -1 errno 35 Resource temporarily unavailable 92514 firefox-bin CALL read(0x29,0x7fffffffb487,0x1) 92514 firefox-bin RET read -1 errno 35 Resource temporarily unavailable 92514 firefox-bin CALL read(0x26,0x7fffffffb467,0x1) 92514 firefox-bin RET read -1 errno 35 Resource temporarily unavailable [... ad infinum ...] Does this arouse any ideas in anyone? I'm using a recent 5.4 on FreeBSD/amd64. Thanks! -mihome | help
