Did you try the libapache2-mod-wo package from packages.wocommunity.org/ubuntu?

Hi Chuck,

unfortunately using a current wonder version does not work either. After compiling the current version from wonder master branch
Apache immediately crashes with a buffer overflow.

The following environment is used:

Linux 3.2.0-35-generic #55-Ubuntu SMP Wed Dec 5 17:42:16 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.6 with Suhosin-Patch mod_ssl/2.2.22 OpenSSL/1.0.1

gcc-4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3
libc6 2.15-0ubuntu10

Stacktrace can be found here for better readability:
https://gist.github.com/michaelsd/5747215

Anybody experiencing the same or similar problems?

Thanks,
Mike

i found a severe problem with one of our Web Servers:

One of the apache processes running mod_webobjects is generating a really high load and the only thing
it does is writing useless data into the error log:

[error] Error receiving content (expected 25463 bytes, got 0)

I googled for the message and the only hit i got was this:

http://serverfault.com/questions/499391/apache-flooded-with-error-logs

In the comments both realize that their server is running mod_webobjects. So i guess there seems to be
some problem here. Is there somebody who can help me with this? The server really takes a hit by this
although still runs stable just with a slower than normal response time.

The system:
Ubuntu 12.04.2 LTS 64 Bit
Apache 2.2

Any help to solve this would really be appreciated!

Thanks, Mike
