Re: System crash related to mod_perl
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I found the problem was happening for the lack of a content length header. Adding this has since fixed the problem.

Re: System crash related to mod_perl
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Sir, Thanks for the help, as it turned out it was the lack of me including a content length that was causing it to hang. This thread can now be disregarded, thanks for everyones time.

Some of the easiest involve sending broken HTML and/or headers, which is where I'd look first. Check particularly things like Content-length for IE and tag nesting for Netscape. > if it works in normal perl, it should work in mod_perl (IMHO). H... Well it looks like it's not doing the same thing when you enable mod_perl that it is doing when you use plain Apache. You need to find out what is different. See the debugging section of the Guide, which you can find at http://perl.apache.org/guide. If you need to post again, first have a look at the docs mentioned in mod_perl/SUPPORT so you can give a better description of your setup. 73, Ged. -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8d+1+dygyS8O4zQ0RAj4IAJ9fnP3aNMHS+Kt3GHE1emYZuGsnWQCgqyxp T0qgqlyftq+J0AT47/Dm8JY= =O62U -END PGP SIGNATURE-

System crash related to mod_perl
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Greetings all, First, note .. I am not suggesting that mod_perl caused the following odd occurance, I am merely suggesting that it is related to mod_perl, and hopefully someone has ran into a similar problem. To begin, I wrote some code to dynamically create an image (jpeg to be specific) of 8 various chars placed randomly. I then spit it out to the browser with mime type 'image/jpeg' and viola. Here is a small code snippet of the final action. - -- Begin -- print $q->header( -type=> 'image/gif', -expires=> 'now' ); print $im->jpeg(100); - -- End This works fine, and so far on all platforms and browsers I have tried. After finishing development of my site, i turned on modperl. Within a few minutes my wife complains her browser has crashed. this problem is occurring _only_ during this image download, _only_ on IE, and _only_ when I have mod_perl enabled. I did not notice the problem as I exclusively use Mozilla, which seems to be working fine. In conclusion, I admit that yes, IE is POS and should not crash when this is occurring, and is strange behavior indeed. But alternatively if it works in normal perl, it should work in mod_perl (IMHO). Hopefully this problem is caused by my possible ignorance and someone can enlighten me. I tested this on my desktop (linux/Mozilla), my wifes machine running win98/IE 5 i believe, and my sons machine running winme. Any help would be greatly appreciated.
