Hi !

We are working with this :
- IBM NetFinity 5100, bi-processor Pentium III
- UnixWare 7.1.1 with loads of patches
- Apache 1.3.23 (also with 1.3.19)
- PHP 4.1.1 (also with 4.0.6)
- Informix SE 7.23.UC1
- ESQL/C 9.21.UC1
- GCC 2.95.2 19991024
- gmake 3.78.1
- Bison 1.32
- Microsoft Windows NT 4.0 SP5/Internet Explorer 5.0

We have regularly some "Segmentation fault" in the Apache error log with this code :
<html><body>
<?
   $connection = ifx_connect("base@tcp", "user", "pwd");
?>
</body></html>

The connection can crashe once for approximately five good connection and sometimes not at all for twenty.

We have placed this code in a .php file and we repeatedly do F5 (actualise) under Internet Explorer until we got the crash.

After checking in the Informix PHP module, we discovered that the crash occured on the EXEC SQL CONNECT ... WITH CONCURRENT TRANSACTION statement, but to no help.

Informix France was contacted but they've got no solution.

It's a UnixWare problem, not a PHP one.
To fix it, just install these PTF files given by Caldera on their web site :
- set71101 (Maintenance set)
- ptf7701b
- ptf7715b
- ptf7716a
- ptf7717a
