Thank you for the report, and for helping us make PHP better.
Code to print the Oracle error message has been added. It may help but from
previous experience I know it's not feasible to expect Oracle libraries to
identify the real root causes of misconfigured systems. So, if the root cause
is
some memory corruption from any subsystem involved, I wouldn't expect the
messages to be reliable.

It's a pity there is no useful information in this bug about the versions and
environments this is seen on. The root problem could be anywhere (including
webserver memory corruption). However since the failure is coming from the
environment setup, it's worth triple-checking the OCI8 environment is set
correctly. Make sure scripts don't use setenv() to set Oracle environment
variables.

Does anyone have a solution / update to this one ? I', experiencing similar
issues on a clients site, and again its not repeatable.

I am seeing this error now for the last few months.
Very frustrating because no way to force it to happen.
As far as I know I changed nothing at all.
There must be some resource limit either in PHP or Oracle that
is not being reported back as being exceeded.
The Apache logs (access and error) contain nothing.
