1.2rc2 on Solaris 9: cups-polld terminating

[Patrick Bosch]

Gerd,

we have had exactly the same problem on Solaris 10 w/ cups 1.2.1. Happened both on SPARC and x86 platforms.

What I found out so far it that the message
E [08/Jun/2006:09:53:17 -0100] cupsdUpdatePolling: all polling processes have exited!

is completely misleading. The cups-polld is still working when the message above is emitted.

Having a look at scheduler/dirsvc.c, we get:

    cupsdLogMessage(CUPSD_LOG_ERROR,
                    "cupsdUpdatePolling: all polling processes have exited!");
    cupsdStopPolling();

So when cupsd THINKS that the polling process has exited, it will kill it. Commenting out the second line, cups-polld continues running. Although the warning message above is still printed every 2-3 minutes, cups-polld is still running and DOES discover changes in remote printers which means it's still communicating with cupsd.

I do not have the time to investigate this any further; i.e. why cupsd thinks cups-polld is basically dead although it is not. So far we can live with the workaround!

Kind Regards
Patrick
