Hello Philipp,

I've noticed for some time, there are nightly regression failures on Solaris 
for the six-vol-test.  The cause of the errors is the following:

12-Aug 01:35 localhost-sd JobId 5: End of medium on Volume "Small0001" 
Bytes=10,451,166 Blocks=162 at 12-Aug-2009 01:35.
12-Aug 01:35 localhost-fd JobId 1: Fatal error: backup.c:1003 Network send 
error to SD. ERR=Not enough space
12-Aug 01:35 localhost-fd JobId 3: Fatal error: backup.c:1003 Network send 
error to SD. ERR=Not enough space
12-Aug 01:35 localhost-sd JobId 3: Fatal error: append.c:244 Network error on 
data channel. ERR=No data available

Now, for me "Not enough space" is a strange error message for network error.  
In looking up Solaris error codes, there is a possibility that this means 
that the swap file is full during that test, and so other functions such as 
the networking start failing.

This is always happening when something like 5 backup jobs are running 
simultaneously.

Would it be possible for you to run the test manually and do a bit of 
monitoring of your system -- probably simply running "top" in a shell window 
will give you an idea if your swap file is filling or if there is some other 
error.

cd bacula/regress
tests/six-vol-test

=== in another shell
top

=== in another shell
monitor total disk availability particularly on the bacula/regress volume.

If you see some signs that your system resources are maxed out, either you can 
increase them, or we can try tweaking the script (I will probably create an 
alternate version) so that it uses less resource (fewer simultaneous jobs).

...

Best regards,

Kern
