tesseract exit when treating multiple images with the baseapi

[GoogleCodeExporter]

Operating System: Ubuntu 8.04

We use tesseract baseapi to treat 6000 regions of 70 different images in 
one process.

When we reach about 6000 calls to TessBaseAPI::TesseractRect, 
tesseract fail to treat the image and exit.

Before each call we init tesseract with TessBaseAPI::SimpleInit(dataPath, 
lang, 0).

After each call we end with TessBaseAPI::End()

Is it a none recoverable error?
Is there anyway to catch the error and prevent the program to exit?

Here is the error message:

We solve the problem by initiating Tesseract once per image despite the fact 
that
we process multiple regions in the image.

So, we call TessBaseAPI::SimpleInit(dataPath, lang, 0) before processing the 
image and
TessBaseAPI::End() when we have finished processing all the image regions.
