Greetings all.
Hope someone can help me out here.

Im using the Clarion ODBC Driver, which randomly crashes on the webserver with:

Error: memory block free’d twice
0A6345FF 0001:000335FF c4otrx.dll
74A0E3DC 0001:0002D3DC ODBC32.dll

Is this a multi dll app?
You can sometimes get this message with multi dll apps with circular references.


#3

Manage to ‘sort this out’
The TPS ODBC driver crashes and corrupts files when it receives multiple simultaneous connections on PHP Apache environment. I limit it to one connection now and its working now.


#4

It should be pointed out you are using the C4 version of the ODBC driver. That’s from like 1997 so the problem may not be present in the existing version.

Hmm, I did check with softvelocity its the latest, its just seems to be named that way

Kajee is correct. The file name is C4*.dll even for the latest versions.
