Hello list, I have a twisted application in production for some time now, running under Fedora Core 6, Python 2.4.4 and twisted 2.4. I know, a little outdated. The process was running fine for some weeks without any problems, although I got this exception in my logs and I really have no idea what it means. The process did not die and is still running ok. 2008/05/13 16:03 BRT [-] Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/twisted/application/app.py", line 278, in run runApp(config) File "/usr/lib/python2.4/site-packages/twisted/scripts/twistd.py", line 197, in runApp app.runReactorWithLogging(config, oldstdout, oldstderr) File "/usr/lib/python2.4/site-packages/twisted/application/app.py", line 131, in runReactorWithLogging reactor.run() File "/usr/lib/python2.4/site-packages/twisted/internet/posixbase.py", line 218, in run self.mainLoop() --- <exception caught here> --- File "/usr/lib/python2.4/site-packages/twisted/internet/posixbase.py", line 229, in mainLoop self.doIteration(t) exceptions.SystemError: unknown opcode Regards, Miguel
