[Xymon] Flushing Stale messages?

I'll answer that myself – yes that means whatever is there can't process the channel fast enough


So, I'll have to go back to my older parser – which is getting this:


Core was generated by `xymond_mysql --pidfile=/var/log/xymon/xymond_history.pid'.
Program terminated with signal 11, Segmentation fault.
#0  0x08049de1 in addnetpeer (peername=0x4f8ca0 "") at xymond_channel.c:140
140 xymond_channel.c: No such file or directory.
in xymond_channel.c
(gdb) where
#0  0x08049de1 in addnetpeer (peername=0x4f8ca0 "") at xymond_channel.c:140
#1  0x00511e9c in ?? ()
#2  0x004f8ca0 in ?? () from /lib/ld-linux.so.2
#3  0x08057190 in stackfgets (buffer=0x80497b0, extraincl=0x2 <Address 0x2 out of bounds>) at stackio.c:434
#4  0x080496c1 in _start ()


Which is getting a null timestamp for some items on stachg channel :/

I have a channel parser than looks at items in the 'stachg' channel

It looks like it's working for me (it parses and does stuff properly)

However – my log is filling up with this:



2013-03-15 11:08:29 Flushed 4 stale messages for 0.0.0.0:0
2013-03-15 11:08:30 Flushed 4 stale messages for 0.0.0.0:0
2013-03-15 11:08:31 Flushed 3 stale messages for 0.0.0.0:0
2013-03-15 11:08:32 Flushed 6 stale messages for 0.0.0.0:0
2013-03-15 11:08:33 Flushed 2 stale messages for 0.0.0.0:0
2013-03-15 11:08:34 Flushed 2 stale messages for 0.0.0.0:0
2013-03-15 11:08:35 Flushed 3 stale messages for 0.0.0.0:0
2013-03-15 11:08:36 Flushed 3 stale messages for 0.0.0.0:0
2013-03-15 11:08:37 Flushed 4 stale messages for 0.0.0.0:0
2013-03-15 11:08:38 Flushed 4 stale messages for 0.0.0.0:0


Is this telling my my parse can not handle the channel in a timely manner, and the message is growing "stale" and I am droping things?
