Hi group,

I'm not sure if I have hit a bug, and if so, if it is worth reporting:

bacula  version
bacula-dir Version: 2.4.4 (28 December 2008) i686-pc-linux-gnu suse 11.0

# uname -a
Linux localhost 2.6.27.21-0.1-default #1 SMP 2009-03-31 14:50:44 +0200
i686 i686 i386 GNU/Linux

In trying to work out why I could not launch the bacula tray monitor
from the menu system, after an update of my system, I then launched
the tray monitor from the command line with using 'strace -f'
(following an earlier suggestion made on the email list)
The tray monitor started and as far as I can see all looks fine at the
GUI level, CPU use fluctuates around approx 0.7%.

The strace log file indicates that somthing might not be 100%.
Specifically I see "lots", i.e. 'EAGAIN (Resource temporarily
unavailable)' occurs 1317 times, of the following type of events
logged:

[pid 22733] gettimeofday({1244356588, 84355}, NULL) = 0
[pid 22733] gettimeofday({1244356588, 84644}, NULL) = 0
[pid 22733] read(3, 0x808a7d4, 4096)    = -1 EAGAIN (Resource
temporarily unavailable)
[pid 22733] gettimeofday({1244356588, 84792}, NULL) = 0
[pid 22733] poll([{fd=3, events=POLLIN}], 1, 425) = 1 ([{fd=3,
revents=POLLIN}])
[pid 22733] read(3,
"\6\0\267\30X\\o\1\246\1\0\0t\0\200\2\0\0\0\0\355\6\225\4\272\0\22\0\20\0\1\0",
4096) = 32
[pid 22733] read(3, 0x808a7d4, 4096)    = -1 EAGAIN (Resource
temporarily unavailable)


After minute or two the strace log file is 10157 lines and size is
> ls -l /tmp/bacula-strace.log
-rw-r--r-- 1 mv users 789371 2009-06-07 16:36 /tmp/bacula-strace.log

The actions I took in the monitor were:
 - open the monitor
 - select the director, fd and sd items
 - exit the monitor gui
 - quit the bacula tray monitor

Is this bug?  known? Should I report it or is this version too old?

Regards
Mark
