I ended up falling back to the previous Debian release. I'm planning to try again in Debian 9. On Tue, Jan 12, 2016 at 9:52 AM, FredB wrote: > Hello, > > I have exactly the same issue that here > https://mail-archives.apache.org/mod_mbox/perl-modperl/201509.mbox/%3CCAC5eUSu85CoiT0MkQvwvxjfrhJcn1

First, let me thank you for your efforts! I doubt I could have come to the bottom of that. Unfortunately, I have been unable to reproduce my problem outside of a production environment and I can't risk pushing a version of perl into production that I've built myself just to test that. As unhelpful

Steve, John: I did a bisect today against perl git, using mod_perl 2.0.9 and apache 2.2.29 to find out where my two issues were caused. It turns out that both of my problems, which were: - panic: attempt to copy freed scalar to and also - segmentation fault caused by a specific "retu

No, I have not. I don't have time to mess with compiling my own version and I certainly don't have time to support a custom version. I always run the version that comes with Debian out of the box. On Mon, Sep 14, 2015 at 1:12 PM, Steve Hay wrote: > Have you tried 5.20.3? This has just been relea

I'll probably deal with this by staying on Debian 7 for the near future. I'll attempt upgrading again in Debian 9. On Mon, Sep 14, 2015 at 10:27 AM, Michael Schout wrote: > On 9/11/15 2:26 PM, John Dunlap wrote: > > I found a lot of stuff like the following in my Apache logs. Is it > > possible

John, Sometimes it's difficult to see what the error is because you can't see the request (doesn't get logged) To get round this - add: * a transhandler which writes a tag (e.g. ST), the request and the PID to the error log * a cleanuphandler which does the same... with a different tag (

Ever since upgrading from Debian 7 - which shipped with Apache 2.2 - to Debian 8 - which shipped with Apache 2.4 - my user base has been reporting that their browsers randomly tell them "No data received". To date, they have not been able to identify any kind of pattern which triggers it. I've been
