Re: [naviserver-devel] Crashing on all versions >4.99.24 on Ubuntu

Brian,


many thanks, the backtrace gives some insights:


The problem happens in a Ns_SetFree operation if set "d8"
triggered by an "ns_set cleanup" during the cleanup of the request.


Something is broken with this nsset.
Can it be that your application package issues "ns_set cleanup" as well?


Do you have a recent version of OpenACS? If so, you can turn on tracing
of the "ns_set" command by adding it to the "traced_cmds".
