4.3.28 xymond problem - Can not bind to listen socket
Good morning (or afternoon...check local listings).
I've been noticing this for quite a while, actually, going back to at least 4.3.27:
Starting xymon: [ OK ] 2017-01-23 11:47:27.577954 xymonlaunch starting 2017-01-23 11:47:27.578110 Loading tasklist configuration from /apps/xymon/server/etc/tasks.cfg 2017-01-23 11:47:27.583564 Loading hostnames [mburger at sysmon ~]$ 2017-01-23 11:47:27.589643 Loading saved state 2017-01-23 11:47:27.724514 Setting up network listener on 0.0.0.0:1984 2017-01-23 11:47:27.724583 Cannot bind to listen socket (Address already in use) 2017-01-23 11:47:27.726431 Task xymond terminated, status 1 2017-01-23 11:47:32.728441 Loading hostnames 2017-01-23 11:47:32.730506 Loading saved state 2017-01-23 11:47:32.828569 Setting up network listener on 0.0.0.0:1984 2017-01-23 11:47:32.828632 Cannot bind to listen socket (Address already in use) 2017-01-23 11:47:32.830513 Task xymond terminated, status 1
I'm guessing that this isn't actually my issue, but what I'm seeing, since upgrading to 4.3.28, is things like being unable to view the list of ghost clients:
Failed to retrieve ghostlist from server
As well as slowness in obtaining client "info", other statuses, or incomplete info returned:
Cannot load host configuration
I've already verified that everything in my installation directory is owned by my Xymon user and group and that the apache user is a member of the xymon group.
Any thoughts?

Belay my last...I found, after having tried to gracefully stop and restart Xymon a few times, that xymond had not stopped...I killed the errant process, restarted it, and now everything's working as it should.

Ah,
That makes sense given the symptoms you were describing. If possible, if you could place a hung errant xymond process into debug mode via -USR2 (or perhaps strace it), it would be helpful to know where it was hanging. Ideally the cleanup and exit should continue and complete under all reasonable circumstances, so if there's a possibility of a hang there I'd definitely like to knock it out.

If it happens again, I'll certainly try. :-)
