We have 2.2.7a running on redhat 9.0 with 256 MB ram. Dual cpus - but only PII 300's. Its not running as a PDC - the PDC is an nt box.
The system is set up as our main print server with 60 odd print queues that service a wide variety of printers. Approx 200 odd windows pc's as clients. The print files themselves can be largish with multi-page docs with lots of graphics. What we are finding is that under certain circumstances (which appears to be a number of big print jobs hitting the server and or users browsing their printers) the smbd processes clog up the cpu - we were running top and vmstat to try to get a handle on what happens when it freezes. These processes start to take an increasing percentage of both cpu and memory with the root owned smbd process topping out at a reported 99% the last time the system froze. These processes hang about in top - they don't drop out as is the case when the system is running correctly We are runing individual logs for each machine and get various error messages in them with the main appearing to be /var/cache/samba/printing.tdb): rec_read bad magic ..... The main log consistently reports the following error message: smbd/oplock_linux.c:linux_init_kernel_oplocks(287) Failed to setup RT_SIGNAL_LEASE handler We are using lprng as we thought it was CUPS creating the problem and since using lprng we are also getting a symptom that on the windows 2000 client, when looking at the print queue, the last job printed remains in the window until aother job pushes it out. The questions I have are whether the system is not sufficient to handle this task. Do we need to split the number of printers over a couple of machines, is there a memory leak. I sthere a way that we can throttle smbd so that it can cope with peaky printing demand. Final question - should I stick with samba mailing list or run this in samba-technical? of course thanks for any help in advance. ------------------------------------------------------------------------- Craig Silva, IT Infrastructure Coordinator Moreland City Council, 90 Bell St. Coburg.
