This seems similar to 15439 and 20109 but it is on iPlanet Web Server 4.1SP10 on Solaris 8.

PHP crashes the webserver SIGSEGV, I have so far been unable to find the exact script that causes the problem, as it seems fairly random. I do however have a backtrace reproduced below:

We've been running for 20+ hours with the snapshot build and haven't had a crash yet. So this seems to have fixed it thanks!!!
