OS: Linux 2.6.24-24 (32 bits) Flash: 11.2 xulrunner 15.0.1 The funny thing is that the software is behaving correctly on a VM but freezes on the real hardware. It makes my debuging experience misarable as the real hardware has only 512MB ram and 512 MB of disk space. I have no luck to move a 600MB libxul.so containing debug symbols!
As I have seen "glitches" with epoll API on old kernels, I will try to recompile libxul with an external libevent lib without epoll. Anyone familiar with the ipc/glue code that wish to assist me to debug my problem, few pointers would be of great help as I have some trouble to understand this code. Links between the browser and the plugin-containers are a pair of pipes, right? Is the RPCChannel code writing RPC msgs does check write() call return value? (It is not clear where this would be done. transport_posix? from the I/O thread?) My AS2 script is periodically calling a webservice (about 2 sec interval), after about a minute everything freezes and I see this: #0 0xb7faf410 in __kernel_vsyscall () #1 0xb7f9a915 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #2 0xb5aa4b5f in PR_WaitCondVar () from /usr/lib/firefox-16.0.1/libnspr4.so #3 0xb5ec108f in ??
