gint fails to produce long sections

Hi, 

We have gint professional latest version. Lately gint fails to produce long sections to PDF if there are more than 5 holes per page. The progress window just disappears after random percentage. When repeating the output, once out of ten we can get lucky to get the PDF after a while (at least 10 mintues).

Even for long section just with a couple of holes, the subsequent output is significantly slower than the first output. So we have to close gint and reopen it to produce the next section in an acceptable speed.

But our biggest issue is not able to get the long sections with more than a couple of holes after repeating attempts. 

We really need immediate help with this.

Regards
