Log errors "unable to open"

[alabamatoy]

I get a flurry of these in my syslog:

Code: Select all

Mar 15 15:17:07 madison zmc_m6[7161]: ERR [Unable to open input rtsp://login:password@192.168.1.149:554/cam/realmonitor?channel=1&subtype=0 due to: Operation now in progress]
Mar 15 15:17:57 madison zmc_m6[7161]: message repeated 5 times: [ ERR [Unable to open input rtsp://login:password@192.168.1.149:554/cam/realmonitor?channel=1&subtype=0 due to: Operation now in progress]]
Mar 15 16:38:23 madison zmc_m6[7919]: ERR [Unable to open input rtsp://login:password@192.168.1.149:554/cam/realmonitor?channel=1&subtype=0 due to: Operation now in progress]
Mar 15 16:41:16 madison zmc_m6[7919]: message repeated 18 times: [ ERR [Unable to open input rtsp://login:password@192.168.1.149:554/cam/realmonitor?channel=1&subtype=0 due to: Operation now in progress]]

But when I look in the /var/log/zm/zma_m6.log and /var/log/zm/zmc_m6.log I see nothing which aligns with any of this.

I am trying to figure out the root cause of these "Unable to open" errors. They seem to occur regularly (but not always!) at the same time each day. I will see a whole bunch of syslog error like shown above, the recordings obviously will have breaks in the stream.

Anyone have any ideas or suggestions? Apologies if this has already been solved, I searched, but didn't find something that looked close to this issue. Point me at it!

Ubuntu 16.04, ZM 1.30.0
