| Doc Text: |
Due to an incorrect use of the memcpy() function in the mod_nss module, running the Apache HTTP Server with this module enabled could cause some requests to fail with the following message written to the error_log file:
request failed: error reading the headers
This update applies a patch to ensure that the memcpy() function is now used in accordance with the current specification, and using the mod_nss module no longer causes HTTP requests to fail.

Description

Any logs from the server would be helpful too. If nothing is happening on the server it might indicate networking issues. If there is something we would want to see it. I meant the other side. I see that the attached log is from the server. Is there anything on the client? I am running these tests on the server ... there isn't a client in the environment at this time. This needs to be fixed in mod_nss. This is caused by a glibc change related to memcpy(). I didn't think this change was done in RHEL 6 otherwise I would have fixed this already. I haven't seen this problem in RHEL 6 myself, though I've only done limited testing. Backported patch from Fedora Jenny, do you have a quick reproducer(I know you said 'intermittent', but just checking) or can you point me to the 'CLI admin commands' you were trying?
