Re: ssl3_write_pending causes apache 1.3 httpd to crash/coredump

["Sailesh Krishnamurthy" <sailesh.krish@xxxxxxxxx>]

Hi,

I got to the technical reason behind this issue. Looks like the fix may be to increase the request timeout 
on the apache side. Can someone tell me which timeout parameter to increase:

The basic cause is thathe segmentation fault being generated by
ssl3_write_pending(). This happens when a timeout occurs during ap_send_fd() or
ap_send_mmap(). The Apache timeout() handler is invoked by the SIGALRM handler,
which closes the connection and frees the SSL context. When the signal handler
finishes and returns to the stack (where we were in the middle of a write
operation somewhere inside of ssl3_write_pending()), ssl3_write_pending()
segfaults when it tries to access the non-existent context.


thx
Sailesh

Unlikely. If you were using a recent version, mod_log_forensic would
allow you to find the problem request. But if you use ancient
versions, you've got to expect problems.
