Segmentation fault when downloading large files

Hello,

I'm using an apache 2.0.39 on a HPUX 11.0 system as a webserver/proxy.
When I try to download large files through the proxy, I get the
following error :

I'm sorry for the example ... ;-))

Anyway, I've tried on several machine that are configured differently (
swap, memory ), but the download stops always around 70 Mb. Does anybody
have an idea what's wrong ? Is there a core I could gdb ( I didn't find
any ) ?

Thanks !

Peter.

Please repost this on the main dev list. This looks like it's caused by
the filter stack not being able to handle large files, not proxy.

Re: Segmentation fault when downloading large files

This look like a filter issue I've seen before; but never could not quite
reproduce. You may want to take this to dev@httpd.apache.org; as this is
most likely related to the filters in apache; and not proxy specific.
