Re: Redirection Location MUST be absolute (was Re: Send a cookie,AND a redirect ?)
Let me bring this back to mod_perl for a sec: >If a CGI script sends out a Location: header that doesn't begin with a >protocol (like http: or ftp:), then it's an *internal* redirect. > >For an internal redirect, the browser never sees the transaction.

Just for clarification, you are speaking _specifically_ about non-mod_perl CGIs, correct? Doing this (via mod_perl): $r->header_out(Location => '/foo/bar/'); causes an external redirect (REPLY headers being sent to the browser), as in: glory:tony[1]% telnet www.uswx.com 80 Trying 207.106.24.123...

Re: Hanging processes SOLVED!
That got it. I cannot thank you enough. The sites are smokin' now.
Recap for interested parties:
* Solaris 2.7
* mod_perl 1.21
Observed bugs:
* occassional httpd processes stop responding
* they stay in 'run' state (via 'top')
* only print 'brk(...)' on occasion via 'truss'
* utilyze all available CPU
* continuously allocate more mem into heap (/usr/proc/bin/pmap)
Cause (Please correct me if this is not correct):
* AUTOLOADing of Apache::Constants::OPT_EXECCGI() can cause this to occur
Fix:
Preload Apache::Constants::OPT_EXECCGI() in either PerlRequire'd file or
section
(Thanks to Chris Remshaw for coming up with it and to Doug MacEachern for
pointing it out to me)
Lessons (re)?learned:
* gdb and debugging versions are your friend
* Check the CVS tree for fixes and reports - who know, you might actually find
the answer
* You definately find better products in the bazaar than in the cathedral

gdb'd several different hanging processes to make sure that this is repeatable. The
only changes were expected (eval # and scalar ref in 'longmess'):
Dont know if this information helps or not, but setting MaxRequestsPerChild to 1
prevents these processes from appearing - setting it even to 2 is enough for them to
start hanging.

Re: Hanging processes
Doug,
Tried what you suggest, but with seemingly disappointing results. (below) The
hangs seem to come _after_ the logging phase - the heap just keep growing and
the process takes up all available CPU, but it doesn't seem to be doing
anything!
This is really getting dis-heartening.
Thanks,

I am having a problem with hanging httpd processes. I have done some AV searches as well as investigated the list archives and did not find any conclusive answer to this problem.

is done statically.
My apologies.

Seg fault on fork w/ PerlModule
I have compiled the following:
Apache 1.3.9
mod_perl 1.21 (PERL_AUTHEN PERL_LOG PERL_STACKED_HANDLERS)
on:
Ultra 10
Solaris 7
with:
gcc 2.95.2 19991024
perl 5.005_03
When starting an httpd process with a 'PerlModule' defined in the conf file,
the process will seg fault when it attempts to fork:
open("/opt/apache/logs/access_log", O_WRONLY|O_APPEND|O_CREAT, 0644) = 3
fcntl(3, F_DUPFD, 0x000F) = 16
close(3)= 0
chdir("/") = 0
fork() = 16024
Incurred fault #6, FLTBOUNDS %pc = 0xD002
siginfo: SIGSEGV SEGV_MAPERR addr=0xD002
Received signal #11, SIGSEGV [default]
siginfo: SIGSEGV SEGV_MAPERR addr=0xD002
*** process killed ***
However, comment out the 'PerlModule' statement, and the process forks fine
and exits:
open("/opt/apache/logs/access_log", O_WRONLY|O_APPEND|O_CREAT, 0644) = 3
fcntl(3, F_DUPFD, 0x000F) = 16
close(3)= 0
chdir("/") = 0
fork() = 16030
llseek(0, 0, SEEK_CUR) = 101628
_exit(0)
I didn't see anything about this on the maillist... get anyone give me an
idea of where I should at least start to track down this problem?
Thanks,
