After migration from Netware 6.5 to OES2sp1 with SLES10sp2 it has been observed that after some time printing stops and we need to restart apache2 service to fix the issue. Now this has been happening very frequently. When the issue is reported I tried printing jobs on couple of printers but didn't get any error and moreover the print queue is also empty. It looks like apache is not able to accept the print requests from clients' PCs and thats why it shows the print job queue as empty. We have also seen that when the issue is reported all the necessary services like novell-ipsmd, novell-idsd, apach2 were showing running.

If anyone has faced similar issue and got success in fixing the same, please respond.
