PHP上的Oracle OCI连接已停止工作-Apache返回ERR_CONNECTION_RESET

Question

All of a sudden ( ... I know ... ) my PHP app has stopped working. When trying to establish a connection with the database I get a connection reset error.

The PHP code is:

 error_log("dbconn.php: db logon " . $un . "/" . $pw . "@" . $db, 0);
 $db_conn = oci_connect($un,$pw, $db); 
 error_log("dbconn.php: returned db logon ");

When I take the connection string and try using sqlplus it works fine.

The php_error_log logs just the first message above.

XAMPP version is 1.8.1 PHP version: 5.4

OCI:

oci8

oci8.persistent_timeout -1  -1
oci8.ping_interval  60  60
oci8.privileged_connect Off Off
oci8.statement_cache_size   20  20

I tried debugging using

error_reporting(E_ALL|E_STRICT);
ini_set('display_errors', 'On');

oci_internal_debug(1); 

At the top of the script, but I cannot find any output.

like I said this was working fine for over a year.

I have tried with different databases and even tried on a completely different server with an untouched LAMPP install and I got the same result there too.

Further to the above, I found this in the Windows Event Viewer:

Faulting application name: httpd.exe, version: 2.4.2.0, time stamp: 0x4fafa3e6

I had a backup of the xampp folder structure. I recopied the php folder from the backup to the xampp folder and it started working again.

I have a strong feeling that some Windows update or other is to blame.
