When printing LOTS on several queues on a client that polls 500 printers from two servers and builing implicit classes from them i get a SIGABRT after about 60 jobs spanning over 6 queues.

CO=1;while [ $CO -lt 50 ];do lpr -P test$CO /testfiles/test0.ps;lpr -P test$CO /testfiles/test1.ps; echo -e "Printing $CO";CO=$[$CO+1];done

This oneliner takes two postscript files and queues them on a printer. And walks through 50 test printers.

Using one file works ok. But when i stress the printers with two or more it crashes according to the previous text.

I believe this is a dupe of STR #1736 and has already been fixed; will verify today...

I am unable to reproduce this problem with current 1.2.x or 1.3.x. Can you test against the current SVN code and let me know if the problem is gone for you as well?

Thanks!

Works with latest 1.2.x svn checkout. Good work.
