Description John E 2004-04-28 14:08:00 UTC

from the logs I see:

(70007)The timeout specified has expired: ap_content_length_filter:
apr_bucket_read() failed

this script workds from command line even as nobody but as a CGI with 2.0.48 and
2.0.49 it timesout.

with 1.3 this works as a CGI ???

exit 5

Comment 1 André Malo 2004-04-28 14:40:36 UTC

Hmm. Does the script writes somehting to stderr (i.e. a lot of stuff)?

Comment 2 John E 2004-04-28 14:59:58 UTC

All the script does is connect to another server with ssh and execute the
command uname.

Comment 3 Paul Querna 2004-07-10 06:57:52 UTC

Works for me here with a few simple tests.

Is there anything else unique about your setup John?

Comment 4 John E 2004-07-12 13:19:37 UTC

No special setup for either Linux RH 8.0 or Solaris 8 and I see the CGI not
completing on apache 2.x but working on 1.3.x ???

Is there anything special to put in the conf files for ssh's executed from a CGI?

Why do I see a difference on success (or not) depending on what major revision I
use as the server?

thanks

Comment 5 Joshua Slive 2004-07-12 13:54:33 UTC

As Andre pointed out, this is almost certainly the cgi-stderr issue.  See bug
22030. Trap the stderr on the script to /dev/null and rerun it verify.

(ie, name your script script2.cgi, then create script1.cgi that looks like

#!/bin/sh
/path/to/script2.cgi 2>/dev/null

and run script1.cgi from the web.)

Comment 6 John E 2004-07-12 15:10:14 UTC

Hi All,

just tried 2.0.50 on RH 8.0 with success with no chagnes to the script that was
failing.

thanks for the fix in 2.0.50.

John
