Forum OpenACS Q&A: Re: naviserver signal 11 core backtrace
Posted by

We just received another core dump. This one is different than the first. The core file was only 9Gig rather than the 22Gig that the first core file was.
Also it's backtrace is different as well. Any insights you might be able to provide are much appreciated.
Thanks,
Marty
