ZServer crash, Zope 2.6.2b3 RH9
RH9 has had major problems with programs that use threads. I just experienced a server crash (ouch!) which looks like it may be due to RH9 threading, but I am not sure. And, of course, there's not much to go on in the logs, there's no chance of reproducing the situation, etc. Basically Zope died at line 241 in ZServer/HTTPResponse.py. This is in the __init__ method of the ChannelPipe class (and "Experimental" pipe from ZPublisher to a ZServer Channel). The error was ZServer Server Error: exception.TypeError, attribute name must be a string: file: $SOFTWAREHOME/ZServer/HTTResponse.py line: 241 repeated many times. ZServer eventually tries to close the channel (uncaptured Python exception), but the error persists. Shutdown of Zope was normal and restarting cleared the problem. Has anyone else seen this kind of behavior? I'll file a bug report on it if it happens again.

Many many people, although maybe not this particular symptom. You can find several solutions in the list archives. (LD_EXPORT_KERNEL to force use of the old thread library, updates fix things.) --jcc -- "My point and period will be throughly wrought, Or well or ill, as this day's battle's fought."
Actually I do just that although it is apparently redundant with the later RH9 kernels. The problem here is RH9 with Python 2.1.3 on a dual Athlon processor machine...which leaves a lot of variables. There are numbrer of other programs, always threading intensive, that fail in my environment under RH9. On Fri, 12 Dec 2003, J. Cameron Cooper wrote:

Thanks.... but I've moved the current stuff back to RH7.3 and have plans to mover everything to Gentoo. On Sat, 13 Dec 2003, Tim Zegir wrote:

This does not look like a threading bug but like memory corruption: The code in "ZServer.HTTPResponse.ChannelPipe.__init__" (at least in my Zope 2.6.2 (final)) cannot raise the above exception under normal circumstances. All attribute accesses are constant, i.e. verified by the compiler. Apparently, one of the attribute name objects changed type -- which can happen when they were overwritten in a memory corruption. -- Dieter
