Can you reproduce the problem at will?
Unfortunately not. Although I have seen the problem on our development
system (where I was testing), the problem is not reproducable. As I said
the live system doesn't behave deterministically either. The conditions
under which is fails are always similar, but it doesn't fail always
under these conditions.
I'd try to use ab or something similar on the dev machine to reproduce it.
Do you know what script/args does it hit when you get this error? e.g. you
could customise the $SIG{__DIE__} handler or put that code above in eval
{} and log the args and the uri of the request that has caused the
problem. However sometimes the error happens on the next request following
the request that has triggered the problem.
Quite often the error line is reported incorrectly. You can always add
something like:
#line 215
$pr->{'code'} = $pr->{r}->slurp_filename;
I'll try that, but I haven't been able to reproduce the problem yet. Can
I be sure that the reported file is right?
Normally it is correct. Unless someone has messed up with the low level C
code that can change that.
For example $$ is readonly, so you get:
That is a good hint. I only had literals on my mind and I didn't think
of special vars.
Our code is not using any specials variables though except %SIG for alarm.
I've used $$ just as an example, any variable can be affected.
If the error occurs, it seem to bubble from apache child to apache child
like an infection (Although it seems to take a pretty long time (like 15
Minutes)). That's why I always figured that this bug must be releated to
source code that is being modified and copied to the children.
Could it be some environment issue? running out of disk space, RAM, etc.?
