This is an intermittent problem I've been running into with PHP and
Ingres.  We're running PHP with Apache on HPUX connecting to an Ingres
2.6
database using the r3 client tools (this happened with the 2.6 tools as
well.)  This isn't due to a corrupted install of something as this
happens on both the primary webserver and the backup webserver (backup
is just a B2000 workstation and has no more that 10-12 users on it at
any one time, the primary has around 100 users on average)

I get a timeout error (maximum execution time of 30 seconds...)
intermittently that is reporting that the line where the page timed out
was where we do an ingres_connect() statement.  We've tried restarting
apache every night, switching to using ingres_pconnect(), bumping up
the number of allowable inbound connections to gcc, bumping up the
number of gcc's running, setting apache httpd processes to die after
handling 10 requests, verifying the the database server's gcc processes
can handle the number of connections, and other steps that I can't
think of off the top of my head.

The problem is intermittent but driving me crazy, I can't find any
information on this anywhere.
