My sybase config for php is as follows:

sybase.allow_persistent =       On
sybase.max_persistent   =       5
sybase.max_links          =       5

Also I am using phplib database classes - which are based on pconnect().
The problem now is that after a short time there are 15 or more PHP processes within the sybase database!
The result is that another Delphi Programm can not longer access the same database, because it can not open a connection when all connections are used by php! (increasing the max num of connections within the sybase db is no real solution to this!)
I wonder about the BROKEN_SYBASE_PCONNECTS define within the source code - is there a known problem which I haven't found within the web/news?

Thanks for help

I experienced the same problem using PHP 4.3.3 on AIX 4.3.3 or Solaris 8 with a DB2/zOS database.
I'm not using --with-ibm-db2 but the unixODBC driver over the CLI interface.
When i run a loadTest, i can see on my SGBD more connexions from the httpdaemon/phpdbuser than allowed in php.ini.
Is there any patch or config i missed to correct this ?
I noticed the following as well, it could be linked to my problem :
the "Active Persistent Links" and "Active Links" sections from phpinfo() always displays 0 in any case.
