I have seen it with solaris 10 sparc. Solaris 9 sparc was fine.

Henrik,
It might be worth checking to make sure these problems are only on Solaris 10 x86 as that is the only architecture I've seen this problem on, sparc seems fine so might help you in narrowing down the problem.

We are running a new installation of Hobbit 4.2 on Solaris 10 running in a non-global zone. Server is a v240 but I don't think that matters here.
The problem here is that our bbgen status turns yellow with fairly high frequency, sometimes multiple times an hour, at (what seem like) random intervals. In the yellow alert bbgen reports: "hobbitd status-board not available"
The reports I've had of this only have one thing in common: They all happen on Solaris 10. So I'm beginning to suspect that maybe Solaris doesn't work quite the way other systems do.
Or perhaps there is a bug, and something special in Solaris triggers it.
Below are the output from some commands/logs. These logs don't really seem to help, so let me know if there is anything else that I can send along to debug this issue.
$BB --debug $BBDISP "hobbitdboard" (with no --debug on a 'failure' I get no output. I'm assuming this is the same cause of the bbgen yellow alert)
Yes.
bbgen --debug --report (this one turned bbgen yellow/unavailable. Note the quick disconnect.) 2006-11-03 09:51:03 load_state() 2006-11-03 09:51:03 Transport setup is: 2006-11-03 09:51:03 bbdportnumber = 1984 2006-11-03 09:51:03 bbdispproxyhost = NONE 2006-11-03 09:51:03 bbdispproxyport = 0 2006-11-03 09:51:03 Recipient listed as '10.xxx.xxx.xxx' 2006-11-03 09:51:03 Standard BB protocol on port 1984 2006-11-03 09:51:03 Will connect to address 10.xxx.xxx.xxx port 1984 2006-11-03 09:51:03 Connect status is 0 2006-11-03 09:51:03 Sent 126 bytes 2006-11-03 09:51:03 Closing connection
Interesting.
Since it seems that this bites you more than most others, I'd like you to do a couple of things for me to figure out what is going on. I need you to add a couple of debugging lines to Hobbit.
First, in the bbdisplay/loaddata.c file, around line 436 you'll find the code that prints out the "hobbitd status board not available" message. It looks like this: errprintf("hobbitd status-board not available\n"); I want you to change that to errprintf("hobbitd status-board not available, code %d\n", hobbitdresult);
Next, in the lib/sendmsg.c file around line 340 is where the code is that receives data from Hobbit. You'll find these lines:
n = recv(sockfd, recvbuf, sizeof(recvbuf)-1, 0); if (n > 0) {
I'd like you to add 8 lines between these two:
n = recv(sockfd, recvbuf, sizeof(recvbuf)-1, 0); if (n < 0) { dbgprintf("recv() returned error: %s\n", strerror(errno)); if (errno == EAGAIN) continue; } if (n == 0) { dbgprintf("recv() gave us 0 bytes\n"); continue; } if (n > 0) {
(it isn't the prettiest of programming, but it does the job for now).
After making these two changes, run "make clean; make" and copy the bbdisplay/bbgen binary into your ~hobbit/server/bin/ directory. Let Hobbit run as normal (with --debug on the bbgen command) and when it fails I am very interested to see what's in the logfile.
