Thanks Nick, If they started misbehaving, what has changed? Any system libraries? Kernel? Hardware and/or drivers? And if so, have you rebuilt apache from clean source? ANSWER: Nothing has changed apart from the OS patches from time to time. And nothing recently. Also this problem has occured 3-4 times this year and generally once every 2-3 months. > 2 of the instances (2.0.48 - Extranet and 2.0.51 - Intranet) have > Netegrity Siteminder Agents ... whatever that is ... ANSWER: It is Apache module which is responsible for Access control (Auth/Az) and SSO and communicates with a backend Policy Server for decision making. > running on them and nothing else (no perl, no > php, nothing.

Do you have anything in Apache to take advantage of that hardware? ANSWER: If you mean, any directive in httpd.conf/ssl.conf to make use of the Accelerator card, yes, I have compiled Apache with a CFLAGS -DSSL_EXPERIMENTAL -DSSL_ENGINE which allows me to use the directive " SSLCryptoDevice cswift" which instructs Apache to offload SSL processing to the hardware. > The management is wanting to know the cause and so do I.

But I believe you need to compile Apache with debug option, and second, the Apache instance does not crash, the parent and one or 2 child processes are often up. But it is not responding to web request. So I guess there will be no core dump !? regards - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Jignesh Badani Intranet/Extranet Technical Services x13563 Nick Kew <nick@xxxxxxxxxxxx> 09/27/2005 10:38 AM Please respond to users@xxxxxxxxxxxxxxxx To users@xxxxxxxxxxxxxxxx cc Subject Re: [users@httpd] Apache2.0.48 Illegal instruction & Segmentation fault issues On Tuesday 27 September 2005 03:36, Jignesh Badani wrote: > Greetings Folks, > > We have been running pretty smoothly 3 instances each of Apache2 (2 of > them on 2.0.48 and the 3rd one is running 2.0.51) for over an year now on > 2 load balanced Solaris 8 (SunFire 480R 2 - Ultra Sparc 3 900Mhz CPU and 4 > GB RAM) boxes.
